See [`docs/websocket-backpressure.md`](docs/websocket-backpressure.md). - -The ingestion metrics are labelled by `network` as well, so a dual-network -deployment reports each network separately: - -| Metric | Type | Labels | -|---|---|---| -| `trades_ingested_total` | Counter | `pair`, `network` | -| `amm_snapshots_total` | Counter | `pool`, `network` | -| `price_snapshots_total` | Counter | `network` | -| `last_trade_timestamp` | Gauge | `pair`, `network` | - -`last_trade_timestamp` is a gauge, so without the `network` label one network's -ingester overwrites the other's value for the same pair — which would make the -staleness signal silently unusable. See -[`docs/ingest-metrics.md`](docs/ingest-metrics.md) for the cardinality notes -(`pairs x networks`) and a staleness alert. - -### Database Connection Pool & Shared Architecture - -> **Important architectural note**: The ingester loops (SDEX, AMM, Soroswap, Snapshot, Aquarius), background workers (retention, partitions), and the HTTP/GraphQL API handlers **run in a single process and share one connection pool**. - -Because deployments often scale across multiple instances, total database connections against Postgres equal: -$$\text{Total Connections} = \text{Instances} \times \text{DB\_POOL\_SIZE} + \text{Superuser/Admin Headroom}$$ - -Configure `DB_POOL_SIZE` and `DB_POOL_TIMEOUT_MS` appropriately so the aggregate across all running instances stays safely beneath PostgreSQL's `max_connections` (typically 100). - -Pool utilisation and exhaustion metrics are exposed on `GET /metrics`: -- `db_pool_connections_in_use`: Number of active connections checked out. -- `db_pool_connections_idle`: Number of idle connections ready in pool. -- `db_pool_connections_waiting`: Requests queued waiting for an available connection. -- `db_pool_exhaustion_errors_total`: Counter incremented whenever connection acquisition times out. Requests encountering pool exhaustion fail with an explicit `503 Service Unavailable` (`DB_POOL_EXHAUSTED`) rather than generic latency or unhandled timeouts. - -### GraphQL Subscriptions (live prices) - -Lens exposes a `priceUpdated(pair)` subscription that pushes a message every time -an ingester (SDEX, Horizon AMM, or Soroswap) records a new price for the pair. -It runs over the same `/graphql` endpoint using the `graphql-transport-ws` -protocol, so any [`graphql-ws`](https://github.com/enisdenjo/graphql-ws) client works. - -```graphql -subscription { - priceUpdated(pair: "XLM/USDC", network: "mainnet") { - pair - price - ts - network - } -} -``` - -```bash -npm install graphql-ws ws -``` - -```typescript -import { createClient } from "graphql-ws"; -import WebSocket from "ws"; // browsers already have WebSocket globally - -const client = createClient({ - url: "ws://localhost:3002/graphql", - webSocketImpl: WebSocket, // omit in the browser -}); - -// `subscribe` returns an unsubscribe function — call it to close the channel. -const unsubscribe = client.subscribe( - { - query: `subscription ($pair: String!, $network: String) { - priceUpdated(pair: $pair, network: $network) { pair price ts network } - }`, - variables: { pair: "XLM/USDC", network: "mainnet" }, - }, - { - next: ({ data }) => console.log("price:", data.priceUpdated), - error: (err) => console.error("subscription error:", err), - complete: () => console.log("subscription closed"), - }, -); - -// Later — stop receiving updates and close the socket cleanly: -// unsubscribe(); -``` - -> **`network` is optional but you almost always want it.** Since #117 every -> enabled network runs its own ingester loop and they all publish to the same -> stream, so omitting it interleaves testnet and mainnet prices for the same -> pair. Every message carries its own `network` field, so an omitted argument -> is safe *if* you read that field — and misleading if you do not. - -> **Note:** the `pair` argument is the canonical `pairKey` (alphabetically -> sorted, e.g. `USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN/XLM`). Use the `listPairs` query to discover -> the exact keys being indexed. Only the pair you subscribe to is delivered; -> updates for other pairs are filtered out server-side. For full protocol handshake details and a raw WebSocket implementation, see [`docs/graphql.md`](docs/graphql.md#live-price-subscriptions-graphql-transport-ws). - -## MCP server - -`npm run mcp:server` starts the Bazaar MCP server ([src/mcp/server.ts](src/mcp/server.ts), wired up in [examples/mcp-server/run.ts](examples/mcp-server/run.ts)). It advertises: - -| Tool | What it does | Spends? | -| --- | --- | --- | -| `bazaar_search` | Reads a Bazaar base URL's `/discovery/resources` or `/discovery/search?q=` and lists what is available. | No | -| `paid_call` | Fetches an x402-gated URL and handles the `402 → sign → retry` loop. | **Yes — it signs with a real Stellar key** | -| `payment_budget` | Reports the configured limits and what is left of today's budget. | No | -| `lens_get_price` | Reads Lens's own aggregated price for a watched pair. | No | - -`payment_budget` appears whenever a spend budget is configured, which the example always sets, and `lens_get_price` only where the server can reach Lens's own price data. Every one of them is served over **either** transport, and the tool list, schemas and error codes are identical whichever you pick. Which transport runs is selected by configuration; **stdio is the default**, so an existing setup needs no changes. - -**⚠️ Warning:** the mainnet key signs with real XLM. Read the configuration, -spending warning, and worked example before running. - -The server signs with a real Stellar key, so it needs `MCP_AGENT_SECRET_KEY_TESTNET` -and `MCP_AGENT_SECRET_KEY_MAINNET` in the environment — keep them in `.env` -(`run.ts` loads it with `dotenv`) rather than in a shell history line or a -client config file that gets shared. Never commit them. Optional spend -controls: `MCP_MAX_PAYMENT_PRICE` (per call, default `$1.00`), -`MCP_DAILY_SPEND_CEILING` (default `$10.00`) and `MCP_SPEND_STATE_FILE` — the -running total survives a restart, because a restart does not refund what the -previous process spent. - -Full documentation: [examples/mcp-server/README.md](examples/mcp-server/README.md) - -### stdio (default) - -For a client that spawns the server itself as a child process — Claude -Desktop, Cursor, or the runnable [agent example](examples/mcp-server/agent.ts) -(`npm run mcp:agent`, which prints discovery and a paid call end to end). - -```bash -npm run mcp:server # reads MCP_TRANSPORT=stdio, talks JSON-RPC on stdin/stdout -``` - -Point a client at the command — the keys come from `.env`, so nothing secret -has to be written into client config.

Do not - expose it on a routable address over plain HTTP: the bearer token and every - paid result cross the wire, so terminate TLS in a reverse proxy and forward - to loopback. -- The token is a credential — the bearer who holds it can spend.

Under **stdio** there is no listener -to scrape, so read the running total from the `payment_budget` tool or the -audit file. - -### WebSocket backpressure - -`/ws` counts a message as sent only once the socket reports the write completed, -and bounds what a client that stops reading can cost: past 256 KiB of queued -bytes updates are coalesced to the newest one, past 1 MiB — or congested for 30s -— the client is closed with `1013` and counted. A truncated feed is visible in -`ws_messages_dropped_total` rather than silent, and one slow client cannot affect -any other. See [`docs/websocket-backpressure.md`](docs/websocket-backpressure.md). - -## Usage Examples - -Lens gates `/price`, `/pools`, and `/candles` behind x402 micropayments on Stellar (testnet by default). The `/status` endpoint is free. - -### 1. Free health check & status monitoring (`/status`) - -`/status` provides a structured, comprehensive health contract separating **process health** (runtime container, memory, uptime) from **data health** (ingestion currency, last ledger, ingest lag). - -```bash -curl http://localhost:3002/status -``` - -```json -{ - "ok": true, - "status": "healthy", - "network": "testnet", - "health": { - "process": "healthy", - "data": "healthy" - }, - "process": { - "uptimeSeconds": 86420, - "memoryUsageMb": 18.42, - "status": "healthy" - }, - "data": { - "lastIndexedLedger": 53842917, - "lastProcessedAt": "2026-05-07T18:45:11.220Z", - "ingestLagSeconds": 4, - "isStale": false - }, - "watchedPairs": ["XLM:native/USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN"], - "lastIndexedLedger": 53842917, - "lastProcessedAt": "2026-05-07T18:45:11.220Z", - "ingestLagSeconds": 4 -} -``` - -#### Health Differentiation & Paging Conditions -- **Process Health vs Data Health:** The HTTP status code distinguishes service availability from data staleness. - - `HTTP 200 OK` (`status: "healthy"`): Both process runtime and data feeds are functioning normally. - - `HTTP 200 OK` (`status: "degraded"`, `health.data: "stale"`): The API server is healthy and responding, but ingestion lag exceeds 300 seconds. **Do not page engineers for intermittent upstream ledger delays.** - - `HTTP 200 OK` (`status: "degraded"`, `health.process: "degraded"`): the port answers but boot has not finished, so not every ingester is running yet. Normal for the first seconds of a deploy — gate rollouts on `/ready`, which stays 503 until boot completes, rather than paging on this. - - `HTTP 503 Service Unavailable` (`pagingCondition: "DATABASE_DOWN"`): Critical infrastructure failure (e.g. Postgres is down or unreachable). **Uptime monitors should page on HTTP 503.** The body carries `error: "Database unavailable"` and nothing more — `/status` is public, so the driver's own message (which can contain the host, the user and the connection string) goes to the server log only. - -#### Monitoring Configuration Example (Datadog / Prometheus / BetterStack) -Configure your synthetic monitor / HTTP probe: -```yaml -# Prometheus Blackbox / Uptime monitor probe example -probe: - target: "http://lens-api.internal:3002/status?network=mainnet" - method: "GET" - expect_status: 200 - alert_conditions: - - severity: critical # Page on-call - condition: "status_code == 503 || body.pagingCondition == 'DATABASE_DOWN'" - - severity: warning # Slack notification only - condition: "body.health.data == 'stale' || body.data.ingestLagSeconds > 300" -``` - -### 2. Paid request without `X-PAYMENT` → `402` with payment requirements - -```bash -curl -i http://localhost:3002/price/XLM/USDC -# HTTP/1.1 402 Payment Required -# content-type: application/json -# -# { -# "x402Version": 1, -# "accepts": [ -# { -# "scheme": "exact", -# "price": "$0.10", -# "network": "stellar:testnet", -# "payTo": "G...your-oracle-address..." -# } -# ], -# "error": "Payment required", -# "description": "Unified SDEX+AMM price with VWAP and best route" -# } -``` - -The `accepts[]` array lists every payment requirement the server will honor. Sign one of them, encode as JSON, base64-encode, and resend with the `X-PAYMENT` header. - -### 3. Paid request with `X-PAYMENT` → `200` with price data - -```bash -# X-PAYMENT is base64(JSON(signed payment payload — see @x402/stellar)) -curl -H "X-PAYMENT: $(cat payment.b64)" \ - http://localhost:3002/price/XLM/USDC -# { -# "assetA": "XLM", -# "assetB": "USDC", -# "pairKey": "XLM:native/USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN", -# "vwap1m": "0.12450000", -# "vwap1h": "0.12410000", -# "volume24h": "1284390.5500", -# "priceChange24h": "0.32", -# "bestRoute": "amm", -# "lastUpdated": "2026-05-07T18:46:02.114Z" -# } -``` - -### 4. Node.js — automatic payment with `@x402/fetch` + `@x402/stellar` - -`@x402/fetch` wraps the native `fetch` so a `402` is intercepted, signed, and retried automatically — your application code looks like a normal request. - -```bash -npm install @x402/fetch @x402/stellar -``` - -```typescript -import { wrapFetchWithPaymentFromConfig } from "@x402/fetch"; -import { ExactStellarScheme } from "@x402/stellar/exact/client"; -import { createEd25519Signer } from "@x402/stellar"; - -// 1. Sign with a Stellar testnet secret (S...). Fund via friendbot first. -const signer = createEd25519Signer( - process.env.STELLAR_SECRET!, // e.g. "SBN...FUNDED..." - "stellar:testnet", -); - -// 2. Wrap fetch — `stellar:*` matches both pubnet and testnet. -const fetchWithPayment = wrapFetchWithPaymentFromConfig(fetch, { - schemes: [ - { - network: "stellar:*", - client: new ExactStellarScheme(signer), - }, - ], -}); - -// 3. Call the gated endpoint. The 402 → sign → 200 dance is automatic. -const res = await fetchWithPayment("http://localhost:3002/price/XLM/USDC"); -const data = await res.json(); -console.log(`XLM/USDC VWAP-1h: ${data.vwap1h}`); -``` - -> **Mainnet:** swap `STELLAR_NETWORK=mainnet` on the server, point the -> client at `stellar:pubnet`, and supply a custom Soroban RPC URL via -> `new ExactStellarScheme(signer, { url: "https://your-rpc..." })`. -> Stellar payments use *ledger-based* expiration (~12 ledgers ≈ 60s), -> not timestamps. - -### 5. GraphQL price query - -```bash -curl -X POST http://localhost:3002/graphql \ - -H "Content-Type: application/json" \ - -d '{"query":"{ getPrice(assetA:\"XLM\", assetB:\"USDC\") { price vwap1h volume24h priceChange24h } }"}' -``` - -Or interactively at [http://localhost:3002/graphiql](http://localhost:3002/graphiql). - -> **Note:** the current `GATED_ROUTES` map in [`src/middleware/x402.ts`](src/middleware/x402.ts) gates `/price`, `/pools`, and `/candles` only — `/graphql` is not gated. If you intend price data from GraphQL to require the same payment as REST, extend `GATED_ROUTES` (or add a per-resolver guard). - -## TypeScript Client - -A typed TypeScript client is generated from [`openapi.yaml`](openapi.yaml) with -[`openapi-typescript`](https://github.com/openapi-ts/openapi-typescript) and -[`openapi-fetch`](https://github.com/openapi-ts/openapi-typescript/tree/main/packages/openapi-fetch). -It is committed at [`clients/typescript`](clients/typescript) — **no type is -hand-written**, so a change to the spec is a change to the client. - -```bash -# Regenerate clients/typescript/src/schema.d.ts from the spec -npm run client:gen - -# Type-check the generated client -npm run client:typecheck -``` - -CI runs `npm run client:gen` and fails if the committed client differs from the -regenerated output, so the client can never drift from `openapi.yaml`. - -```typescript -import { createLensClient } from "./clients/typescript/src/index.js"; - -const client = createLensClient({ baseUrl: "http://localhost:3002" }); - -const { data, error } = await client.GET("/price/{assetA}/{assetB}", { - params: { path: { assetA: "XLM", assetB: "USDC" } }, -}); -if (error) throw new Error(`request failed: ${error}`); - -// `data` is `AggregatedPrice`, derived from the spec. -console.log(`XLM/USDC vwap1h: ${data?.vwap1h}`); -``` - -A runnable version lives in -[`clients/typescript/src/example.ts`](clients/typescript/src/example.ts); run it -against a local server with `npx tsx clients/typescript/src/example.ts`. - -## Documentation -Detailed system design and data flow diagrams can be found in the [Architecture Overview](docs/architecture.md). -Lens also *publishes* prices: [`docs/sep40-oracle-publisher.md`](docs/sep40-oracle-publisher.md) covers the SEP-40 contract in `oracle/contract/`, the deviation-and-interval publication policy in `src/publish/`, deployment, and key handling. -The API specification is available in [OpenAPI 3.0 format](openapi.yaml) and is auto-published to GitHub Pages at https://miracle656.github.io/lens/openapi.json. - -Operators: start with the [Operations runbook](docs/RUNBOOK.md) — what runs, how each external dependency degrades, how to check ingestion health via `/status` and `/metrics`, the known failure modes with their symptoms, and deploy/rollback procedures. - -Operational docs: [HTTP metrics](docs/http-metrics.md), [ingest metrics](docs/ingest-metrics.md), [websocket backpressure](docs/websocket-backpressure.md), [health probes](docs/health.md), [GraphQL](docs/graphql.md). -The MCP server also advertises read-only [resources](docs/mcp-resources.md) — the watched pairs, venues, this OpenAPI document, and service status — each with a stable URI and freshness an agent can cache against. - -## Examples - -The [oracle relay example](examples/oracle-relay/README.md) shows a minimal Soroban contract plus a Node relay that reads Lens prices and pushes them on chain. - -The [price alert bot example](examples/alert-bot/README.md) shows an "if XLM > X notify me" bot built on the WebSocket price stream — see the [cookbook walkthrough](docs/cookbook/alert-bot.md). - -## Docker Quickstart -The fastest way to get Lens running locally is with Docker: - -```bash -# Start Lens, Postgres, and Redis -docker compose up -d - -# Check health -docker compose ps -``` -The API will be available at `http://localhost:3002`. Database migrations run automatically on startup. - -## Quick Start (Manual) - -```bash -# 1. Start PostgreSQL + Redis -docker-compose up -d - -# 2. Install dependencies -npm install - -# 3.

Requests encountering pool exhaustion fail with an explicit `503 Service Unavailable` (`DB_POOL_EXHAUSTED`) rather than generic latency or unhandled timeouts. + +### GraphQL Subscriptions (live prices) + +Lens exposes a `priceUpdated(pair)` subscription that pushes a message every time +an ingester (SDEX, Horizon AMM, or Soroswap) records a new price for the pair. +It runs over the same `/graphql` endpoint using the `graphql-transport-ws` +protocol, so any [`graphql-ws`](https://github.com/enisdenjo/graphql-ws) client works. + +```graphql +subscription { + priceUpdated(pair: "XLM/USDC", network: "mainnet") { + pair + price + ts + network + } +} +``` + +```bash +npm install graphql-ws ws +``` + +```typescript +import { createClient } from "graphql-ws"; +import WebSocket from "ws"; // browsers already have WebSocket globally + +const client = createClient({ + url: "ws://localhost:3002/graphql", + webSocketImpl: WebSocket, // omit in the browser +}); + +// `subscribe` returns an unsubscribe function — call it to close the channel. +const unsubscribe = client.subscribe( + { + query: `subscription ($pair: String!, $network: String) { + priceUpdated(pair: $pair, network: $network) { pair price ts network } + }`, + variables: { pair: "XLM/USDC", network: "mainnet" }, + }, + { + next: ({ data }) => console.log("price:", data.priceUpdated), + error: (err) => console.error("subscription error:", err), + complete: () => console.log("subscription closed"), + }, +); + +// Later — stop receiving updates and close the socket cleanly: +// unsubscribe(); +``` + +> **`network` is optional but you almost always want it.** Since #117 every +> enabled network runs its own ingester loop and they all publish to the same +> stream, so omitting it interleaves testnet and mainnet prices for the same +> pair.

It advertises: + +| Tool | What it does | Spends? | +| --- | --- | --- | +| `bazaar_search` | Reads a Bazaar base URL's `/discovery/resources` or `/discovery/search?q=` and lists what is available. | No | +| `paid_call` | Fetches an x402-gated URL and handles the `402 → sign → retry` loop. | **Yes — it signs with a real Stellar key** | +| `payment_budget` | Reports the configured limits and what is left of today's budget. | No | +| `lens_get_price` | Reads Lens's own aggregated price for a watched pair. | No | + +`payment_budget` appears whenever a spend budget is configured, which the example always sets, and `lens_get_price` only where the server can reach Lens's own price data. Every one of them is served over **either** transport, and the tool list, schemas and error codes are identical whichever you pick. Which transport runs is selected by configuration; **stdio is the default**, so an existing setup needs no changes. + +**⚠️ Warning:** the mainnet key signs with real XLM. Read the configuration, +spending warning, and worked example before running. + +The server signs with a real Stellar key, so it needs `MCP_AGENT_SECRET_KEY_TESTNET` +and `MCP_AGENT_SECRET_KEY_MAINNET` in the environment — keep them in `.env` +(`run.ts` loads it with `dotenv`) rather than in a shell history line or a +client config file that gets shared. Never commit them. Optional spend +controls: `MCP_MAX_PAYMENT_PRICE` (per call, default `$1.00`), +`MCP_DAILY_SPEND_CEILING` (default `$10.00`) and `MCP_SPEND_STATE_FILE` — the +running total survives a restart, because a restart does not refund what the +previous process spent. + +Full documentation: [examples/mcp-server/README.md](examples/mcp-server/README.md) + +### stdio (default) + +For a client that spawns the server itself as a child process — Claude +Desktop, Cursor, or the runnable [agent example](examples/mcp-server/agent.ts) +(`npm run mcp:agent`, which prints discovery and a paid call end to end). + +```bash +npm run mcp:server # reads MCP_TRANSPORT=stdio, talks JSON-RPC on stdin/stdout +``` + +Point a client at the command — the keys come from `.env`, so nothing secret +has to be written into client config.

Do not + expose it on a routable address over plain HTTP: the bearer token and every + paid result cross the wire, so terminate TLS in a reverse proxy and forward + to loopback. +- The token is a credential — the bearer who holds it can spend. Keep it out + of URLs, logs, and shell history; rotate it if it leaks. +- Requests are stateless: no `Mcp-Session-Id` is issued and each `POST` is + served by a fresh transport, so a client cannot hold a session open across + requests. Every MCP message must be a `POST` (`GET` returns `405`, which + spec-compliant clients treat as "no server-initiated stream"). Bodies are + capped at 1 MiB. +- The daily spend ceiling is shared across everything this process serves, so + one HTTP client cannot spend past a budget another one already used up. + +#### Payment spend metrics + +What the agent spent is scrapeable from the same listener, at `GET /metrics`, +guarded by the same bearer token — it is operator data about a key that moves +money, so there is no anonymous scrape: + +```bash +curl -sS http://127.0.0.1:3003/metrics \ + -H "Authorization: Bearer $MCP_HTTP_AUTH_TOKEN" +``` + +| Metric | Type | Labels | +| --- | --- | --- | +| `mcp_payment_attempts_total` | Counter | `host`, `network`, `outcome` | +| `mcp_payment_amount_usd_total` | Counter | `host`, `network` | +| `mcp_payment_unquantified_total` | Counter | `host`, `network` | + +A refused payment is an attempt (`outcome="failure"`) and adds nothing to +`mcp_payment_amount_usd_total`. `host` may only be a value from +`MCP_METRIC_HOSTS` and `network` only one from `MCP_METRIC_NETWORKS` (default +`stellar:testnet,stellar:pubnet` — the networks this server signs for): +Prometheus series are permanent, so anything outside an allow-list is reported +as `unknown` instead of letting one caller mint a time series per URL an agent +tries. Amounts that are not a USD money string cannot join the USD sum, so they +are counted in `mcp_payment_unquantified_total` rather than dropped silently. +Per-payment detail — full URL, transaction hash, asset, error code — is in the +`MCP_PAYMENT_LEDGER_FILE` audit trail, which keeps the real host whatever the +allow-list says. + +`MCP_HTTP_PATH` cannot be `/metrics`; the process exits at boot rather than +answering MCP and Prometheus on one path. Under **stdio** there is no listener +to scrape, so read the running total from the `payment_budget` tool or the +audit file. + +### WebSocket backpressure + +`/ws` counts a message as sent only once the socket reports the write completed, +and bounds what a client that stops reading can cost: past 256 KiB of queued +bytes updates are coalesced to the newest one, past 1 MiB — or congested for 30s +— the client is closed with `1013` and counted. A truncated feed is visible in +`ws_messages_dropped_total` rather than silent, and one slow client cannot affect +any other. See [`docs/websocket-backpressure.md`](docs/websocket-backpressure.md). + +## Usage Examples + +Lens gates `/price`, `/pools`, and `/candles` behind x402 micropayments on Stellar (testnet by default). The `/status` endpoint is free. + +### 1.

Nothing serves. | -| Down at **runtime** | Queries throw → affected routes return 5xx. `/status` itself queries the DB, so it fails too. | -| Where you see it | `GET /status` refused/500 **and `GET /ready` → 503 with `checks.postgres.status: "down"`** (the probe also asserts the schema exists via `to_regclass('public.indexer_state')`, so a reachable-but-unmigrated database reports not-ready too); `GET /metrics` → `http_requests_total{status_class="5xx"}` rising, `db_query_duration_seconds` tail; pino error logs. | -| Recovery | Restore the nightly dump (`docs/backup-restore.md`, produced by `db-backup.yml`), or re-ingest from chain — Lens data is re-derivable by ingesting again (`docs/DEPLOY_MAINNET.md`). | - -### Redis — `REDIS_URL` - -**Used for:** the price cache (`getCachedPrice`/`setCachedPrice`, TTL -`PRICE_CACHE_TTL`, default 10 s), BullMQ queues/workers, cross-instance -WebSocket pub/sub. - -| | Behaviour | -|---|---| -| Down at **boot** | Soft: `redis unavailable, continuing without cache`. The API still serves — **every cache read falls back to Postgres** (`getCachedPrice` catches and returns `null`), writes are best-effort (swallowed). Per-worker effects: **aggregate refresh is skipped with no fallback**; retention and partition maintenance fall back to hourly in-process timers; ws cross-instance fan-out is skipped. | -| Down at **runtime** | The client rejects commands immediately (`enableOfflineQueue: false`, `src/redis.ts` — no request hangs waiting for a connection), reconnects with backoff capped at 60 s, and logs at most **one `redis connection error` per minute**. Reads keep falling back to Postgres. BullMQ's own connections (separate ioredis instances) log `[ioredis] Unhandled error event` while away and pause the queue-driven jobs. | -| What breaks concretely | • No cache: every `/price` request recomputes from Postgres — correct, just slower.
• **`price_aggregates` freeze** if the aggregate-refresh worker is not running (skipped at boot, or paused while BullMQ cannot reach Redis). Consumers: `/price/:assetA/:assetB/history`, `/screener`, and the GraphQL aggregate queries — their buckets stop advancing while `/price/:assetA/:assetB` keeps serving live values (it computes VWAP from `price_points` on a cache miss — `getAggregatedPrice`, `src/aggregator/vwap.ts`).
• Multi-instance WebSocket fan-out stops: clients still receive events published by *their own* instance (the local `priceEmitter` subscription always works — `src/ws/fanout.ts`), but not events from other instances.
• **Readiness fails**: `GET /ready` PINGs Redis and reports `down` (503) while Redis is away — the instance leaves rotation even though reads still work from Postgres (`READINESS_REDIS_CHECK=false` excludes Redis from readiness). | -| Where you see it | `X-Cache: MISS` on every `/price` response (`src/api/rest.ts`); `/screener` and `/price/.../history` stop moving; `aggregate refresh worker skipped (redis unavailable)` / `redis connection error` in logs; `GET /ready` → 503 with `checks.redis.status: "down"`; `ws_messages_sent_total` low on one instance while ingestion metrics are healthy. **`GET /metrics` has no Redis gauge** — the cache signal is the `X-Cache` response header, the readiness signal is `/ready`. | -| Note on #345 | The issue title says Redis is "noticed once and never again"; today's code reconnects forever with capped backoff and throttled logging (`src/redis.ts`). The genuinely unfixed part is the **missing aggregate-refresh fallback** (see §4). | - -### Stellar Horizon — `HORIZON_URL` / `HORIZON_URL_` - -**Used for:** SDEX trade ingestion and Horizon AMM snapshots. - -| | Behaviour | -|---|---| -| Down / rate-limited | No 429-specific handling anywhere in the ingest path (#348). SDEX fetch failures are caught inside `fetchSdexTrades` (`src/ingest/venues/sdex.ts`), logged as `error fetching trades`, and the cycle continues having ingested nothing. Failures that escape an adapter fail the cycle and trigger exponential backoff 10 s → 60 s cap: `venue adapter cycle failed; retrying` (`src/ingest/venues/runner.ts`). | -| Where you see it | `GET /status` → `ingestLagSeconds` grows; `GET /metrics` → `trades_ingested_total` flat, `time() - last_trade_timestamp` growing (staleness alert recipe: `docs/ingest-metrics.md`). | -| Recovery | Automatic: backoff retries forever; ingestion resumes from the persisted cursor in `indexer_state` (`setIndexerCursor`), so no trades are skipped once Horizon recovers — only the outage window is missing. | - -### Soroban RPC, Soroswap factory, Aquarius API — `RPC_URL*`, `SOROSWAP_FACTORY_ADDRESS*`, `AQUARIUS_*` - -**Used for:** AMM pool reserves/snapshots (Soroswap), Aquarius pool discovery, -Reflector oracle reads (on demand, not a background loop). - -| | Behaviour | -|---|---| -| Bad/missing config | `config.ts` warns naming the env var and disables the feature; the adapter logs `venue adapter is disabled — ingester not started` and returns. | -| Down at runtime | Cycle failures back off like above. Aquarius is quieter: `if (!res.ok) return []` (`src/ingest/venues/aquarius.ts`) — **a failing API returns empty results with no error**. | -| Where you see it | `GET /metrics` → `amm_snapshots_total` flat; `/pools` pool `timestamp` goes stale; the `ammPrice` half of `/price/:assetA/:assetB` stops updating while `sdexPrice` keeps moving. | - -### x402 facilitator — `X402_FACILITATOR_URL` (default `https://x402.org/facilitator`) - -**Used for:** verifying payments on the gated routes (`/price`, `/pools`, -`/candles` — `GATED_ROUTES` in `src/middleware/x402.ts`).

Nothing is persisted or re-queued — **the event is gone** (#342). | -| Where you see it | The `webhook` pino logger only. **`GET /metrics` exports no webhook series at all** — silence on `/metrics` does not mean delivery worked. | - -### Keep-alive monitor (production on Render free tier) - -`docs/DEPLOY_MAINNET.md`: Render free services sleep after ~15 min idle, so an -UptimeRobot monitor pings `GET /status` every 5 minutes. - -| | Behaviour | -|---|---| -| Monitor stops / misconfigured | The service sleeps → `GET /status` connection refused **and ingestion sleeps with it** — staleness follows. | -| Where you see it | `/status` refused while nothing else is wrong; UptimeRobot's own alerting. | - -### Environment variables - -There is **no central env validation** (#338): `WATCHED_PAIRS` format throws at -startup (`parseWatchedPairs`, `src/config.ts` → fatal exit 1), everything else -is read directly from `process.env` at first use.

The cause is only inferable from the last log line before the exit. | -| 2 | **Shutdown is not graceful** (#347) | There is **no** `SIGTERM`/`SIGINT` handler anywhere in `src/`; the process exits immediately. In-flight requests are cut and WebSocket clients are dropped **without a close frame**. | During any deploy/restart: WS clients see an abnormal closure (no `1000/1001` close frame), `ws_clients_total` disappears, `http_requests_total` stops mid-request. | -| 3 | **Horizon rate limiting is not handled** (#348) | No 429 branch exists in the ingest path. SDEX 429s surface as a caught error → log `error fetching trades` → `null`, and the loop retries on the normal poll interval without backoff or accounting. | `GET /status` `ingestLagSeconds` grows; `GET /metrics` `trades_ingested_total` flat + stale `last_trade_timestamp`; repeating `error fetching trades` or `venue adapter cycle failed; retrying` in the logs. | -| 4 | **A single ingester cycle has no deadline** (#351) | `startVenueAdapter` runs `while (true)` and awaits every watched pair **sequentially** with no cycle-level timeout (`src/ingest/venues/runner.ts`); there is no per-cycle upper bound. | The whole network's ingestion quietly spreads/stalls: `last_trade_timestamp` ages and `/status.ingestLagSeconds` grows **while no `venue adapter cycle failed` line appears** — no error, just lag. | -| 5 | **Webhook retries have no jitter** (#341) | Delay is exactly `2^(attempt-1) × 1000` ms (`retryDelayMs`, `src/alerts/delivery.ts`) — subscribers triggered together retry together. | Bursts of `webhook delivery failed after retries` (logger `webhook`) arriving in lockstep after any upstream blip; `GET /metrics` has **no** webhook series to graph this. | -| 6 | **A webhook that fails 3 times disappears** (#342) | After 3 attempts (or any 4xx on the first) the failure is logged and dropped — no persistence, no queue, no dead-letter. | The subscriber silently never receives the threshold event; the only trace is the `webhook` log line. Nothing on `/metrics` moves. | -| 7 | **DB pool is default-sized and unmeasured** (#339) | `new Pool({connectionString})` with pg defaults (max 10 connections); instrumentation is only the `db_query_duration_seconds` histogram — no pool gauge exists (`src/db.ts`, `src/metrics.ts`). | Under saturation both `db_query_duration_seconds` and `http_request_duration_seconds` shift right together (the timer includes pool wait); `GET /metrics` offers **no waiter/pool gauge** to confirm it. | -| 8 | **Env vars are not centrally validated** (#338) | Only `WATCHED_PAIRS` parsing throws at startup; every other variable is consumed lazily at first use. | Misconfiguration surfaces at first use — see the symptom table in §2 (bad `REDIS_URL` → `X-Cache: MISS` forever; unset `ORACLE_PAYMENT_ADDRESS` → gating silently off; unset `ADMIN_TOKEN` → admin routes always 401). | -| 9 | **Redis away at boot: aggregate refresh has no fallback** (the unfixed half of #345) | Retention and partition maintenance fall back to hourly in-process timers when their BullMQ schedule fails at boot; the **aggregate-refresh worker does not** — it is skipped and never retried for the life of the process (`src/index.ts`). | `aggregate refresh worker skipped (redis unavailable)` at boot, then: `/screener` and `/price/:assetA/:assetB/history` (and GraphQL aggregate queries) freeze while `/price/:assetA/:assetB` keeps serving live prices from `price_points`. | - ---- - -## 5. Deploy, rollback, and what a deploy interrupts - -### How a deploy happens - -- **Production** (`docs/DEPLOY_MAINNET.md`): Render web service built from this - repo/image, env vars in the Render dashboard only, Neon Postgres, managed - Redis, UptimeRobot keep-alive on `/status`. -- **Self-hosted / local**: `docker compose up -d --build` (image built by the - multi-stage `Dockerfile`, `CMD npm start`). -- In both cases the boot sequence in §1 applies — **including the automatic - `prisma migrate deploy`**. - -### What a deploy interrupts - -1. **The schema changes to whatever the committed migrations say.** Step 1 of - boot runs `prisma migrate deploy` (`src/db/migrate.ts`) before the API - listens. Unlike the `db push` it replaced, it applies only migrations that - are in `prisma/migrations` and that a reviewer read — so a destructive change - reaches production because someone merged the SQL, not because a diff decided - it. It is still the one irreversible part of any deploy: read the pending - migrations before deploying, and take the backup path (rollback step 3) first - if any of them drops a column or a table. - - The corollary of dropping `db push` is that drift is no longer self-healing. - A column present in `schema.prisma` but missing from the live database is - **not** added at boot any more — `migrate deploy` has nothing pending to - apply, and `assertSchemaValid()` only covers the five core tables in - `EXPECTED_SCHEMA`. Fix it with a committed migration; see the one-time check - in [`docs/database-migrations.md`](database-migrations.md). -2. **The API is down until `listen` returns, and not *ready* until boot ends.** - Single instance ⇒ no rolling deploy; compose allows 20 s (`start_period`) - before healthchecks fail. `GET /ready` stays 503 from process start until - `markBootComplete()` — gate rollouts on `/ready`; `/live` alone only proves - the event loop turns. -3. **No graceful shutdown** (#347, §4): in-flight requests are cut and WS - clients are dropped without a close frame. -4. **Ingestion pauses for the restart, then resumes from persisted cursors.** - Cursor state lives in `indexer_state`, writes are idempotent - (`skipDuplicates` in `upsertPricePoints`, `ON CONFLICT DO NOTHING` on - snapshots), so replay after restart is safe; the gap is the trades that - happened while the process was down (visible as missing `price_points` for - that window and a lag spike in `/status`). -5. **In-memory state is lost:** rate-limit windows (429 counters reset), WS - client list, the ingesters' last-price map (the webhook previous-price - baseline restarts, so the first post-restart tick compares against itself). - Redis, being external, keeps the price cache warm across a deploy. -6. **Maintenance jobs re-run safely.** Prune and partition maintenance run once - at boot regardless, the hourly schedules are re-registered, and BullMQ jobs - are at-least-once — safe here because every job is an upsert/prune. - -### How to roll back - -1. **App code:** redeploy the previous known-good revision — - Render: roll back to the previous deploy in the dashboard; - self-hosted: `git checkout && docker compose up -d --build`. -2. **Schema:** migrations are forward-only — Prisma generates no down-migration - — so rolling back the code does not roll back the schema. Roll *forward*: - commit a migration that reverses the change and deploy it - (`npm run db:deploy`). Do **not** reach for `prisma db push` from the old - checkout: it is gone from `package.json` for a reason, and a push against a - database that now has migration history leaves the two disagreeing. If the - previous revision cannot run against the new schema, the honest options are a - reversing migration or a restore from the dump — **take the backup path - (step 3) first** if either direction removes data. -3. **Data (if a bad deploy or its auto-migration destroyed rows):** restore the - nightly dump per [`docs/backup-restore.md`](backup-restore.md) — dumps are - produced daily at 03:00 UTC by `.github/workflows/db-backup.yml`, - age-encrypted, 14-day retention. Alternatively re-ingest: Lens data is - re-derivable from chain (`docs/DEPLOY_MAINNET.md`), bounded only by how far - back the cursors point. -4. **Config:** env vars live in the host (Render dashboard / `.env`), not in - the repo. Keep the previous env set alongside the previous image — a code - rollback with the new env is only half a rollback. -5. **Verify the rollback:** - ```bash - curl -s https:///ready # 200 {"ok":true,...} - curl -s https:///status # ok:true, lag small - curl -s -o /dev/null -w '%{http_code}\n' https:///price/XLM/USDC - # 200 (ungated) or 402 (x402-gated) — not 5xx - curl -s https:///metrics | grep -E 'trades_ingested_total|last_trade_timestamp' - SMOKE_MAX_AGE_SECONDS=120 npm run smoke -- https:// - ``` - ---- - -## 6.

External dependencies and what degrades without them + +### PostgreSQL — `DATABASE_URL` + +**Used for:** everything durable — `price_points`, `price_snapshots`, +`pool_snapshots`, `price_aggregates`, `indexer_state`, pairs, webhooks, +API keys/usage. It is the source of truth; Redis is only a cache +("Redis is a cache and a job broker, not a source of truth" — comment in `src/index.ts`). + +| | Behaviour | +|---|---| +| Down at **boot** | `pgPool.connect()` rejects → `fatal startup error` → **process exits 1**. Nothing serves. | +| Down at **runtime** | Queries throw → affected routes return 5xx. `/status` itself queries the DB, so it fails too. | +| Where you see it | `GET /status` refused/500 **and `GET /ready` → 503 with `checks.postgres.status: "down"`** (the probe also asserts the schema exists via `to_regclass('public.indexer_state')`, so a reachable-but-unmigrated database reports not-ready too); `GET /metrics` → `http_requests_total{status_class="5xx"}` rising, `db_query_duration_seconds` tail; pino error logs. | +| Recovery | Restore the nightly dump (`docs/backup-restore.md`, produced by `db-backup.yml`), or re-ingest from chain — Lens data is re-derivable by ingesting again (`docs/DEPLOY_MAINNET.md`). | + +### Redis — `REDIS_URL` + +**Used for:** the price cache (`getCachedPrice`/`setCachedPrice`, TTL +`PRICE_CACHE_TTL`, default 10 s), BullMQ queues/workers, cross-instance +WebSocket pub/sub. + +| | Behaviour | +|---|---| +| Down at **boot** | Soft: `redis unavailable, continuing without cache`. The API still serves — **every cache read falls back to Postgres** (`getCachedPrice` catches and returns `null`), writes are best-effort (swallowed). Per-worker effects: **aggregate refresh is skipped with no fallback**; retention and partition maintenance fall back to hourly in-process timers; ws cross-instance fan-out is skipped. | +| Down at **runtime** | The client rejects commands immediately (`enableOfflineQueue: false`, `src/redis.ts` — no request hangs waiting for a connection), reconnects with backoff capped at 60 s, and logs at most **one `redis connection error` per minute**. Reads keep falling back to Postgres. BullMQ's own connections (separate ioredis instances) log `[ioredis] Unhandled error event` while away and pause the queue-driven jobs. | +| What breaks concretely | • No cache: every `/price` request recomputes from Postgres — correct, just slower.
• **`price_aggregates` freeze** if the aggregate-refresh worker is not running (skipped at boot, or paused while BullMQ cannot reach Redis). Consumers: `/price/:assetA/:assetB/history`, `/screener`, and the GraphQL aggregate queries — their buckets stop advancing while `/price/:assetA/:assetB` keeps serving live values (it computes VWAP from `price_points` on a cache miss — `getAggregatedPrice`, `src/aggregator/vwap.ts`).
• Multi-instance WebSocket fan-out stops: clients still receive events published by *their own* instance (the local `priceEmitter` subscription always works — `src/ws/fanout.ts`), but not events from other instances.
• **Readiness fails**: `GET /ready` PINGs Redis and reports `down` (503) while Redis is away — the instance leaves rotation even though reads still work from Postgres (`READINESS_REDIS_CHECK=false` excludes Redis from readiness). | +| Where you see it | `X-Cache: MISS` on every `/price` response (`src/api/rest.ts`); `/screener` and `/price/.../history` stop moving; `aggregate refresh worker skipped (redis unavailable)` / `redis connection error` in logs; `GET /ready` → 503 with `checks.redis.status: "down"`; `ws_messages_sent_total` low on one instance while ingestion metrics are healthy. **`GET /metrics` has no Redis gauge** — the cache signal is the `X-Cache` response header, the readiness signal is `/ready`. | +| Note on #345 | The issue title says Redis is "noticed once and never again"; today's code reconnects forever with capped backoff and throttled logging (`src/redis.ts`). The genuinely unfixed part is the **missing aggregate-refresh fallback** (see §4). | + +### Stellar Horizon — `HORIZON_URL` / `HORIZON_URL_` + +**Used for:** SDEX trade ingestion and Horizon AMM snapshots. + +| | Behaviour | +|---|---| +| Down / rate-limited | No 429-specific handling anywhere in the ingest path (#348). SDEX fetch failures are caught inside `fetchSdexTrades` (`src/ingest/venues/sdex.ts`), logged as `error fetching trades`, and the cycle continues having ingested nothing. Failures that escape an adapter fail the cycle and trigger exponential backoff 10 s → 60 s cap: `venue adapter cycle failed; retrying` (`src/ingest/venues/runner.ts`). | +| Where you see it | `GET /status` → `ingestLagSeconds` grows; `GET /metrics` → `trades_ingested_total` flat, `time() - last_trade_timestamp` growing (staleness alert recipe: `docs/ingest-metrics.md`). | +| Recovery | Automatic: backoff retries forever; ingestion resumes from the persisted cursor in `indexer_state` (`setIndexerCursor`), so no trades are skipped once Horizon recovers — only the outage window is missing. | + +### Soroban RPC, Soroswap factory, Aquarius API — `RPC_URL*`, `SOROSWAP_FACTORY_ADDRESS*`, `AQUARIUS_*` + +**Used for:** AMM pool reserves/snapshots (Soroswap), Aquarius pool discovery, +Reflector oracle reads (on demand, not a background loop). + +| | Behaviour | +|---|---| +| Bad/missing config | `config.ts` warns naming the env var and disables the feature; the adapter logs `venue adapter is disabled — ingester not started` and returns. | +| Down at runtime | Cycle failures back off like above. Aquarius is quieter: `if (!res.ok) return []` (`src/ingest/venues/aquarius.ts`) — **a failing API returns empty results with no error**. | +| Where you see it | `GET /metrics` → `amm_snapshots_total` flat; `/pools` pool `timestamp` goes stale; the `ammPrice` half of `/price/:assetA/:assetB` stops updating while `sdexPrice` keeps moving. | + +### x402 facilitator — `X402_FACILITATOR_URL` (default `https://x402.org/facilitator`) + +**Used for:** verifying payments on the gated routes (`/price`, `/pools`, +`/candles` — `GATED_ROUTES` in `src/middleware/x402.ts`). Only active when +`ORACLE_PAYMENT_ADDRESS` is set; otherwise the plugin logs +`[oracle] ORACLE_PAYMENT_ADDRESS not set — x402 gating disabled` and the gated +routes are **free**. + +| | Behaviour | +|---|---| +| Unreachable / verify throws | Caught in the preHandler → **402** `{error: "Payment verification failed", reason: ...}` (fails closed). | +| Settle fails | Settlement is async after the response is sent; failure is only logged `[oracle] x402 settle error` — the request was already served. | +| Where you see it | Paying clients suddenly receive 402s; `GET /metrics` → `x402_payments_received_total` stops incrementing; `webhook`-style pino logs from the `oracle` logger. | + +### Subscriber webhook endpoints (outbound HTTP) + +**Used for:** threshold alerts registered via `POST /webhooks`. + +| | Behaviour | +|---|---| +| Failing subscriber | 10 s timeout, **3 attempts** with delays 1 s, 2 s (`retryDelayMs`, `src/alerts/delivery.ts`), **no jitter** (#341). A 4xx stops immediately; final failure is only logged `webhook delivery failed after retries`. Nothing is persisted or re-queued — **the event is gone** (#342). | +| Where you see it | The `webhook` pino logger only. **`GET /metrics` exports no webhook series at all** — silence on `/metrics` does not mean delivery worked. | + +### Keep-alive monitor (production on Render free tier) + +`docs/DEPLOY_MAINNET.md`: Render free services sleep after ~15 min idle, so an +UptimeRobot monitor pings `GET /status` every 5 minutes. + +| | Behaviour | +|---|---| +| Monitor stops / misconfigured | The service sleeps → `GET /status` connection refused **and ingestion sleeps with it** — staleness follows. | +| Where you see it | `/status` refused while nothing else is wrong; UptimeRobot's own alerting. | + +### Environment variables + +There is **no central env validation** (#338): `WATCHED_PAIRS` format throws at +startup (`parseWatchedPairs`, `src/config.ts` → fatal exit 1), everything else +is read directly from `process.env` at first use.

Issue numbers are the open +tracking issues for the batch this runbook was filed in. + +| # | Failure mode | What happens today (code) | Where you see it | +|---|---|---|---| +| 1 | **Unhandled rejection kills the process** (#344) | There is **no** `unhandledRejection`/`uncaughtException` handler anywhere in `src/`; Node's default is to exit — with no application log line for the cause. | Process gone: `GET /status` connection refused, compose healthcheck fails, `http_requests_total` flatlines while the container restarts. The cause is only inferable from the last log line before the exit. | +| 2 | **Shutdown is not graceful** (#347) | There is **no** `SIGTERM`/`SIGINT` handler anywhere in `src/`; the process exits immediately. In-flight requests are cut and WebSocket clients are dropped **without a close frame**. | During any deploy/restart: WS clients see an abnormal closure (no `1000/1001` close frame), `ws_clients_total` disappears, `http_requests_total` stops mid-request. | +| 3 | **Horizon rate limiting is not handled** (#348) | No 429 branch exists in the ingest path. SDEX 429s surface as a caught error → log `error fetching trades` → `null`, and the loop retries on the normal poll interval without backoff or accounting. | `GET /status` `ingestLagSeconds` grows; `GET /metrics` `trades_ingested_total` flat + stale `last_trade_timestamp`; repeating `error fetching trades` or `venue adapter cycle failed; retrying` in the logs. | +| 4 | **A single ingester cycle has no deadline** (#351) | `startVenueAdapter` runs `while (true)` and awaits every watched pair **sequentially** with no cycle-level timeout (`src/ingest/venues/runner.ts`); there is no per-cycle upper bound. | The whole network's ingestion quietly spreads/stalls: `last_trade_timestamp` ages and `/status.ingestLagSeconds` grows **while no `venue adapter cycle failed` line appears** — no error, just lag. | +| 5 | **Webhook retries have no jitter** (#341) | Delay is exactly `2^(attempt-1) × 1000` ms (`retryDelayMs`, `src/alerts/delivery.ts`) — subscribers triggered together retry together. | Bursts of `webhook delivery failed after retries` (logger `webhook`) arriving in lockstep after any upstream blip; `GET /metrics` has **no** webhook series to graph this. | +| 6 | **A webhook that fails 3 times disappears** (#342) | After 3 attempts (or any 4xx on the first) the failure is logged and dropped — no persistence, no queue, no dead-letter. | The subscriber silently never receives the threshold event; the only trace is the `webhook` log line. Nothing on `/metrics` moves. | +| 7 | **DB pool is default-sized and unmeasured** (#339) | `new Pool({connectionString})` with pg defaults (max 10 connections); instrumentation is only the `db_query_duration_seconds` histogram — no pool gauge exists (`src/db.ts`, `src/metrics.ts`). | Under saturation both `db_query_duration_seconds` and `http_request_duration_seconds` shift right together (the timer includes pool wait); `GET /metrics` offers **no waiter/pool gauge** to confirm it. | +| 8 | **Env vars are not centrally validated** (#338) | Only `WATCHED_PAIRS` parsing throws at startup; every other variable is consumed lazily at first use. | Misconfiguration surfaces at first use — see the symptom table in §2 (bad `REDIS_URL` → `X-Cache: MISS` forever; unset `ORACLE_PAYMENT_ADDRESS` → gating silently off; unset `ADMIN_TOKEN` → admin routes always 401). | +| 9 | **Redis away at boot: aggregate refresh has no fallback** (the unfixed half of #345) | Retention and partition maintenance fall back to hourly in-process timers when their BullMQ schedule fails at boot; the **aggregate-refresh worker does not** — it is skipped and never retried for the life of the process (`src/index.ts`). | `aggregate refresh worker skipped (redis unavailable)` at boot, then: `/screener` and `/price/:assetA/:assetB/history` (and GraphQL aggregate queries) freeze while `/price/:assetA/:assetB` keeps serving live prices from `price_points`. | + +--- + +## 5. Deploy, rollback, and what a deploy interrupts + +### How a deploy happens + +- **Production** (`docs/DEPLOY_MAINNET.md`): Render web service built from this + repo/image, env vars in the Render dashboard only, Neon Postgres, managed + Redis, UptimeRobot keep-alive on `/status`. +- **Self-hosted / local**: `docker compose up -d --build` (image built by the + multi-stage `Dockerfile`, `CMD npm start`). +- In both cases the boot sequence in §1 applies — **including the automatic + `prisma migrate deploy`**. + +### What a deploy interrupts + +1. **The schema changes to whatever the committed migrations say.** Step 1 of + boot runs `prisma migrate deploy` (`src/db/migrate.ts`) before the API + listens. Unlike the `db push` it replaced, it applies only migrations that + are in `prisma/migrations` and that a reviewer read — so a destructive change + reaches production because someone merged the SQL, not because a diff decided + it. It is still the one irreversible part of any deploy: read the pending + migrations before deploying, and take the backup path (rollback step 3) first + if any of them drops a column or a table. + + The corollary of dropping `db push` is that drift is no longer self-healing. + A column present in `schema.prisma` but missing from the live database is + **not** added at boot any more — `migrate deploy` has nothing pending to + apply, and `assertSchemaValid()` only covers the five core tables in + `EXPECTED_SCHEMA`. Fix it with a committed migration; see the one-time check + in [`docs/database-migrations.md`](database-migrations.md). +2. **The API is down until `listen` returns, and not *ready* until boot ends.** + Single instance ⇒ no rolling deploy; compose allows 20 s (`start_period`) + before healthchecks fail. `GET /ready` stays 503 from process start until + `markBootComplete()` — gate rollouts on `/ready`; `/live` alone only proves + the event loop turns. +3. **No graceful shutdown** (#347, §4): in-flight requests are cut and WS + clients are dropped without a close frame. +4. **Ingestion pauses for the restart, then resumes from persisted cursors.** + Cursor state lives in `indexer_state`, writes are idempotent + (`skipDuplicates` in `upsertPricePoints`, `ON CONFLICT DO NOTHING` on + snapshots), so replay after restart is safe; the gap is the trades that + happened while the process was down (visible as missing `price_points` for + that window and a lag spike in `/status`). +5. **In-memory state is lost:** rate-limit windows (429 counters reset), WS + client list, the ingesters' last-price map (the webhook previous-price + baseline restarts, so the first post-restart tick compares against itself). + Redis, being external, keeps the price cache warm across a deploy. +6. **Maintenance jobs re-run safely.** Prune and partition maintenance run once + at boot regardless, the hourly schedules are re-registered, and BullMQ jobs + are at-least-once — safe here because every job is an upsert/prune. + +### How to roll back + +1. **App code:** redeploy the previous known-good revision — + Render: roll back to the previous deploy in the dashboard; + self-hosted: `git checkout && docker compose up -d --build`. +2. **Schema:** migrations are forward-only — Prisma generates no down-migration + — so rolling back the code does not roll back the schema. Roll *forward*: + commit a migration that reverses the change and deploy it + (`npm run db:deploy`). Do **not** reach for `prisma db push` from the old + checkout: it is gone from `package.json` for a reason, and a push against a + database that now has migration history leaves the two disagreeing. If the + previous revision cannot run against the new schema, the honest options are a + reversing migration or a restore from the dump — **take the backup path + (step 3) first** if either direction removes data. +3. **Data (if a bad deploy or its auto-migration destroyed rows):** restore the + nightly dump per [`docs/backup-restore.md`](backup-restore.md) — dumps are + produced daily at 03:00 UTC by `.github/workflows/db-backup.yml`, + age-encrypted, 14-day retention. Alternatively re-ingest: Lens data is + re-derivable from chain (`docs/DEPLOY_MAINNET.md`), bounded only by how far + back the cursors point. +4. **Config:** env vars live in the host (Render dashboard / `.env`), not in + the repo. Keep the previous env set alongside the previous image — a code + rollback with the new env is only half a rollback. +5. **Verify the rollback:** + ```bash + curl -s https:///ready # 200 {"ok":true,...} + curl -s https:///status # ok:true, lag small + curl -s -o /dev/null -w '%{http_code}\n' https:///price/XLM/USDC + # 200 (ungated) or 402 (x402-gated) — not 5xx + curl -s https:///metrics | grep -E 'trades_ingested_total|last_trade_timestamp' + SMOKE_MAX_AGE_SECONDS=120 npm run smoke -- https:// + ``` + +--- + +## 6.

Decoupling schema validation from schema migration prevents distributed boot race conditions. + +3. **Time-Series Partitioning Compatibility:** + Lens's high-frequency tables (such as `price_points` and `price_aggregates`) require composite primary keys (e.g. `[id, timestamp]`) and time-series optimizations. + +## Startup Verification Guard (#352) + +To ensure that running code never crashes at request time due to missing columns or unapplied schema changes: +- `src/db/schemaVerify.ts` runs on boot via `assertSchemaValid()` / `verifyDatabaseSchema()`. +- It performs a low-overhead inspection against PostgreSQL `information_schema.tables` and `information_schema.columns`. +- If an expected table or column is absent, it fails fast and names the missing entities. +- `/ready` and `/status` can query `verifyDatabaseSchema()` to isolate instances before they receive live traffic. + +## Path Forward: Transitioning to `prisma migrate` + +When moving to formal multi-region enterprise production deployments: +1. Generate baseline migration from the current production database: `npx prisma migrate diff --from-empty --to-schema-datamodel prisma/schema.prisma --script > prisma/migrations/0_init/migration.sql`. +2. Mark baseline as applied: `npx prisma migrate resolve --applied 0_init`. +3. Enforce CI/CD pipeline validation using Prisma Migrate with the schema startup verification guard serving as the runtime barrier. diff --git a/docs/graphql.md b/docs/graphql.md index b1c2ea12..9eb41c67 100644 --- a/docs/graphql.md +++ b/docs/graphql.md @@ -1,443 +1,443 @@ -# Lens GraphQL API Documentation - -Lens exposes a high-performance GraphQL API alongside its REST interface, powered by Fastify and [mercurius](https://mercurius.dev).
