Xata Is Joining ClickHouse

Xata is joining ClickHouse to combine its Postgres branching and provisioning technology with ClickHouse Managed Postgres, a service built for fast, sustained production workloads on local NVMe storage. The case for the combination is that AI coding agents and increasingly automated software development make database access a bottleneck: every pull request, agent run, and deployment preview needs an isolated environment with realistic data. Conventional database copies are slow and costly at terabyte scale. Xata says its copy-on-write branches can be created in about three seconds without duplicating the underlying data, while each branch gets independent compute. Its platform also offers instant provisioning, anonymization of production data, and scale-to-zero, which suspends idle databases and wakes them on connection.

These features make it practical to create branches for testing and run large fleets of small databases economically; Xata says some AI-focused customers already create thousands of branches weekly. The technology relies on Xatastor, a distributed storage engine using ZFS and NVMe/TCP, and warm compute pools that avoid provisioning delays. ClickHouse brings high-performance Postgres for long-lived workloads, alongside its analytical database and work integrating Postgres and ClickHouse through replication and a unified query layer. Xata customers can continue using the service for now, and new sign-ups remain open. The companies plan to add branching and an agentic tier to ClickHouse Managed Postgres, then migrate Xata customers after feature parity, aiming to minimize disruption.
