Altinity Project Antalya Builds for ClickHouse® Release Notes

Altinity’s open-source Project Antalya is a new branch of ClickHouse® designed to combine Clickhouse’s lightning-fast queries with Data Lakes that use Iceberg as the table format, store data as columns in Parquet, all hosted on S3-compatible storage.

See the project's README, roadmap (for 2026 and 2025), and feature matrix for more information.

As of February, 2026, Project Antalya is not for production use.
