Three open-source Greenplum forks that picked up active development after Greenplum went closed source in 2024: - Greengage (https://github.com/GreengageDB/greengage) Installed from the upstream greengage6.deb (6.30.1) in ubuntu:22.04. - OpenGPDB (https://github.com/open-gpdb/gpdb) Installed from the upstream greenplum-db-6 .deb (6.29.8) in ubuntu:22.04. - WarehousePG (https://github.com/warehouse-pg/warehouse-pg) No prebuilt binaries; built from source (7.4.0-WHPG) in rockylinux:9. All three reuse the cloudberry layout: privileged docker container, single-host 14-segment cluster via gpinitsystem, gpfdist load, psql query. data-size runs du inside the container so it reports actual bytes (the cloudberry copy reads /data0 on the host, which isn't bind-mounted). Resolves #888 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Test plan
cd greengage && ./benchmark.shend-to-end (install → load → query sweep → concurrent QPS).cd opengpdb && ./benchmark.shend-to-end.cd warehousepg && ./benchmark.shend-to-end (first install builds from source, ~10–20 min)../data-sizereports a value >5 GB after./loadso the benchmark driver's partial-load guard is satisfied.🤖 Generated with Claude Code
