Copy-on-Write Branching

ClickHouse has acquired database startup Xata to bring instant provisioning, copy-on-write branching and scale-to-zero compute into ClickHouse Managed Postgres, aiming at a Postgres platform built for AI agents. Xata customers and sign-ups remain unchanged for now, with migration to ClickHouse Managed Postgres planned over time. The deal targets database workflows emerging as the bottleneck as agents generate ever more code.
