Docker Compose setup for PostgreSQL high availability cluster with custom tool for benchmarking. It provides ready-to-use environment for testing and benchmarking various PostgreSQL high availability (HA) cluster configurations. This setup is intended for testing purposes and is not recommended for production use. However, it can be used as a starting point for building your own production-ready PostgreSQL HA cluster.
The repository includes multiple Docker Compose files, each tailored for a specific cluster topology. You will find
these configurations in the postgres-ha-smr and postgres-ha-sharding directories. Below are simplified diagrams
of the prepared cluster topologies.
After starting your cluster, you can use included pgload tool to initialize the database and run benchmarks. pgload
supports both replication and sharding modes and can be configured via command-line options. You can also run
ready-to-use compose file to start benchmarking desired configuration.
docker compose -f benchmark/compose.yml up -dor for the sharded cluster:
docker compose -f benchmark/compose.yml -f benchmark/compose.sharding.yml up -d
