Overview v26.3

Understand how EDB packages and distributes ClickHouse, what's covered in this documentation, and what falls outside its scope.

How EDB provides ClickHouse

EDB Postgres AI for ClickHouse isn't a fork. EDB builds and distributes the open-source ClickHouse binary, identical to the upstream release, repackaged as RPMs, container images, and a Kubernetes operator for enterprise Linux distributions, and supported by EDB.

EDB's contribution is:

  • Building the official open-source ClickHouse source at a pinned upstream release
  • Packaging the binary as RPMs, a container image, and a Kubernetes operator, distributed through the EDB package repository
  • Integrating ClickHouse into the EDB Postgres AI Analytics pillar alongside WarehousePG and the EDB Postgres Lakehouse
  • Providing EDB support

The ClickHouse query engine, SQL dialect, table engines, and performance characteristics are identical to the upstream open-source release.

Verify you're running an EDB-packaged build:

SELECT value FROM system.build_options WHERE name = 'VERSION_OFFICIAL';

The output includes (EDB Build) for EDB-packaged releases.
