Reliable Data Replication from PostgreSQL to ClickHouse using PeerDB

This article demonstrates how to reliably replicate data from PostgreSQL to ClickHouse using PeerDB, a change data capture (CDC) solution specializing in PostgreSQL. It compares self-hosted open-source PeerDB with a fully managed version integrated into ClickHouse Cloud (via ClickPipes). Core concepts like creating peers, mirrors, and data transformations are explained, along with a step-by-step deployment and configuration guide. Whether using the open-source or managed route, PeerDB offers a highly performant and reliable data replication solution for PostgreSQL and ClickHouse users.
