YCSB-C

Yahoo! Cloud Serving Benchmark in C++, a C++ version of YCSB (https://github.com/brianfrankcooper/YCSB/wiki)

Quick Start

To build YCSB-C on Ubuntu, for example:

sudo apt-get install libtbb-dev
git clone git@github.com:yanghy233/YCSB-C.git
cd YCSB-C
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
make
mkdir ramdisk_path rocksdb_disk_path ycsb-leveldb
./ycsba.sh

Use the following command to get the max physical thread count of your systems.

echo $(nproc)

Run Workload A with Rocksdb, an implementation of the database, for example:

./ycsbc -db cruisedb -threads 32 -P workloads/workloada.spec 1>res/w1.out 2>res/w1.txt
./ycsbc -db rocksdb -threads 32 -P workloads/workloada.spec 1>res/w1.out 2>res/w1.txt

See help by invoking ./ycsbc without any arguments.

Note that we do not have load and run commands as the original YCSB. Specify how many records to load by the recordcount property. Reference properties files in the workloads dir.

Supported Databases

• LevelDB
• RocksDB
• CruiseDB

Note that CruiseDB and Rocksdb will be install in the same directory(/usr), so you should only install one of them or remove the other one.

Note for Rocksdb

If you want to use Rocksdb, you should modify db/rocks_db.cc

//  Status s = db_->TbBegin(cf_, code);
//  assert(s.ok());

Then recompile the project.

Before compile YCSB-C

Note that if you want to test Rocksdb or CruiseDB, you should compile and install first.

cd rocksdb # or cd cruisedb
make static_lib share_lib DEBUG_LEVEL=0 -j$(nproc)
sudo DEBUG_LEVEL=0 make uninstall
sudo DEBUG_LEVEL=0 make install
