ClickHouse Buys Xata to Add Branching to Managed Postgres

On November 9, 2026, ClickHouse announced that it had acquired Xata and made its Managed Postgres service generally available, with plans to add Xata’s instant database branching and scale-to-zero technology. Financial terms were not disclosed.
The acquisition connects two distinct approaches to Postgres. ClickHouse Managed Postgres uses local NVMe storage and targets high-throughput, long-lived production workloads. Xata said its service is built to provision large numbers of small, short-lived databases containing production-like data, with independent compute for each branch. Both platforms run unmodified PostgreSQL, giving the planned integration a common database foundation.
For existing users, nothing changes in the short term, and Xata continues to accept new sign-ups. The company plans to integrate its features into Managed Postgres and eventually migrate customers once there is feature parity, with the goal of avoiding service impact.
Branching Without Full Copies
Xata says its copy-on-write branching avoids duplicating underlying data, allowing a database containing multiple terabytes to be branched in around three seconds. Each child branch has its own compute on a different physical node, isolating it from the parent. Under that model, 50 branches of a 1TB database are billed much closer to 1TB than 50TB because customers pay for the differences rather than full copies. Idle databases can also suspend automatically and wake on the next connection in about one second.
A GitHub integration can automatically create an isolated database branch for every pull request, allowing changes to be tested in CI/CD pipelines before merging. The same branch-per-run model gives coding agents isolated environments without affecting production, while anonymization removes sensitive information before production data leaves production. Xata reports that Sapien, Enginy, David AI, Runner AI and LoopAI each create thousands of database branches every week, an adoption measure for those workflows.
General Availability Changes Commercial Terms
ClickHouse says Managed Postgres is generally available on AWS, while GCP remains in private preview with general availability coming soon. Over the 10 months preceding the announcement, its local NVMe-backed Postgres service delivered up to tenfold performance improvements. It now supports hundreds of production customers, including enterprises running multi-terabyte workloads.
WalShadow consumes physical write-ahead logs for sub-second replication to ClickHouse, ClickPipes provides an alternative at no additional cost, and pg_clickhouse lets applications query ClickHouse through the Postgres interface. With general availability, the beta discount ends and backup storage and public network egress become billable. Native ClickHouse connectivity and ClickPipes replication remain included, and ClickHouse expects the additional charges to be modest for most customers.
Integration Roadmap Targets Agent Workloads
ClickHouse expects copy-on-write storage, automatic idling and scale-to-zero to make it economical to run millions of intermittently active Postgres environments. Its integration plan has two paths: instant branches and clones for local NVMe-backed production Postgres, and a dedicated Managed Postgres tier for agent sandboxing, agent memory and other agent-first workloads. The first path couples short-lived branch environments with production storage, while the second addresses workloads where elastic compute and ephemeral environments matter.
David AI, identified by both companies as a joint customer, migrated from Neon to ClickHouse Managed Postgres and uses Xata branching so developers and AI coding agents can build and test in parallel. Its current two-platform arrangement illustrates the workflow ClickHouse intends to make native within one platform.
The acquisition gives ClickHouse the engineering team and storage technology for that expansion, while Xata’s customers gain a planned route into ClickHouse’s production database and analytics platform. The near-term test is execution: integrating branching and serverless operation, reaching feature parity for Xata customers and completing their migration without disrupting existing workloads.
