This series of articles explores replicating data from PostgreSQL to ClickHouse, two databases with a common open-source heritage that excel at different workloads. Part one focuses on using PeerDB for self-managed replication, while part two looks at ClickPipes for a fully managed solution. PostgreSQL is ideal for transactional workloads, while ClickHouse is preferred for analytics. An interesting use case arises when businesses run both databases to support the same application. PeerDB, known for its fast and scalable CDC solutions for PostgreSQL, is now integrated with ClickHouse. The content includes details on data replication tools, self-managed vs fully managed solutions, core concepts, and a walkthrough for setting up PeerDB.
