Greengage DB is an open-source MPP database based on Greenplum, maintained by the GreengageDB community after Greenplum went closed source in 2024. https://github.com/GreengageDB/greengage

The benchmark runs Greengage inside a privileged Ubuntu 22.04 docker container, so the host can be any distro with docker. The install script fetches the upstream greengage6.deb (no source build) and initializes a single-host, 14-segment cluster via gpinitsystem.

The other scripts (start/stop/check/load/query) docker exec into the running container.

To run the test:

./benchmark.sh
