ClickHouse® software is a columnar database engine for real-time analytics. It ingests millions of events per second and makes them queryable immediately, delivering sub-second aggregations across billions of rows. It's the right engine for workloads that demand sub-second answers on live, high-volume data.
EDB Postgres AI for ClickHouse delivers EDB-signed packages, SLAs, CVE response, and break/fix expertise for open-source ClickHouse. Not a fork. Not a managed service. Run your own ClickHouse deployment with enterprise support from EDB.
EDB Postgres AI for ClickHouse is based entirely on open-source ClickHouse. For a full breakdown of what's covered and what requires a separate commercial offering, see the overview page.
What ClickHouse® is for
ClickHouse is optimized for workloads where speed beats everything else:
- High-volume analytics where data arrives seconds or minutes ago and must be queryable immediately
- IoT monitoring, ad-tech bidding, fraud detection, and similar time-critical workloads
- User-facing dashboards with thousands of concurrent users on live data
- Sub-second rollups on events, logs, and telemetry
- Postgres observability, storing and querying metrics from Postgres databases at scale
ClickHouse® and WarehousePG
ClickHouse and WarehousePG answer different questions and complement each other within the EDB Postgres AI Analytics pillar.
ClickHouse answers "What's happening right now?": sub-second aggregations on high-volume, recent data, optimized for few-column scans across huge single tables.
WarehousePG answers "What happened?": complex multi-table joins, enrichment, data modeling, and batch analytics where accuracy matters more than speed.
Apache Iceberg® acts as the shared source of truth between them: data written by either engine is accessible to both, with no copies or ETL pipelines between them.
