The PostgreSQL driver for SBK supports multiple writers and multiple readers performance benchmarking. But, the End to End Latency benchmarking is not supported. The PostgreSQL driver uses the auto incrementing index are primary key to support multiple writers. The PostgreSQL driver uses the JDBC for IO operations.
As an example, to start the PostgreSQL storage server as a container is as follows:
docker run -p 127.0.0.1:5432:5432/tcp --name kmg-postgres -e POSTGRES_USER=root -e POSTGRES_PASSWORD=root -d postgres
An example, SBK benchmarking command is
./build/install/sbk/bin/sbk -class postgresql -size 100 -writers 1 -seconds 60
by default, the SBK uses the url: jdbc:postgresql://localhost:5432/postgres, and default table name is 'test' the default username is 'root' and the default password is 'root'.
Sample SBK PostgeSQL write output is follows
kmg@kmgs-MacBook-Pro SBK % ./build/install/sbk/bin/sbk -class postgresql -size 100 -writers 1 -seconds 60
