Open House 2026 Day 1: ロックインなきリアルタイムデータと、チームが次に構築できるもの

ClickHouse Open House 2026 Day 1 featured a series of announcements across ClickHouse Cloud, Postgres, distributed query execution, AI agents, observability, and lakehouse interoperability. Key highlights included the public beta release of ClickHouse Postgres, which offers over five times the transactions per second compared to AWS RDS, and significant improvements in query performance through multi-stage distributed queries, reducing TPC-H SF100 execution time nearly by half. ClickHouse Agents, powered by Claude, entered public beta, providing a native chat experience and a no-code agent builder. Enhancements to interoperability included support for writing to Microsoft OneLake and Unity Catalog, enabling bidirectional workflows between ClickHouse and external lakehouse systems. Updates to ClickHouse Cloud aimed at improving resilience, observability, schema management, and developer tools were also unveiled, with features like cross-region replication, Monitoring v2, and a new Schema Management and Optimization tool. The day concluded with the announcement of Langfuse V4, improving query performance by up to 200 times, and the introduction of ClickStack Cloud, a serverless observability platform, alongside a new partner program called House Mates.
