@@ -203,12 +207,12 @@ For both processing types, the service handles two primary task phases:
 
 - **For Update Ingestion:**
   - Updates catalog layers
-  - Creates seed jobs and tasks
+  - Creates a cache deletion job whose tasks delete the ingested footprint's tile ranges from MapProxy's redis cache
 
 - **For Swap Update Ingestion:**
   - Updates catalog layers
   - Handles layer updates in MapProxy when required
-  - Creates seed jobs and tasks
+  - Creates a cache deletion job whose task wipes the layer's entire redis cache prefix
