PostgreSQL + ClickHouse as the Open Source unified data stack

A recently launched managed service integrates PostgreSQL and ClickHouse into a unified data stack, allowing teams to manage transactional and analytical workloads without complex pipelines. PostgreSQL acts as the system of record, while ClickHouse handles analytics at scale, facilitated by open-source components like PeerDB for data streaming and pg_clickhouse for seamless query offloading. This setup, which can be implemented using change data capture or split-writes patterns, enables efficient real-time analytics and is suitable for various applications including retail and financial systems. The managed version simplifies deployment and maintenance by offering a comprehensive solution under one ClickHouse Cloud account, enhancing scalability and reliability. By leveraging both databases, teams can efficiently manage growing data volumes and complex queries, establishing a new standard for open data stacks where PostgreSQL and ClickHouse collaboratively fulfill different roles.
