Postgres change data capture. It monitors your databases and produces an event for every row-level change, streaming those events into Apache Kafka. What Is Multi-Writer Change Data Capture (CDC)? Change Data Capture (CDC) is a pattern for tracking and propagating data changes in real time, powering use cases like downstream synchronization, auditing, event streaming, and real-time analytics.

The last step will be changing max_wal_senders which is the maximum number of simultaneously running WAL sender processes available for Gluesync to work correctly with PostgreSQL CDC. Change data capture Gluesync consumes changes from PostgreSQL by implementing the CDC (Change data capture) technique to read transaction logs from PostgreSQL replication slots technology starting from version 10; From the books: Change data capture (CDC) is at the heart of any real-time data replication or database streaming solution. 3 days ago · PostgreSQL: Stores the application data and writes every change into its Write-Ahead Log (WAL). It enables: crash recovery replication change data capture backup systems point-in-time recovery In many ways, WAL is the foundation that many PostgreSQL features are built on. Log-based CDC with automatic schema handling and self-healing pipelines. Test different CDC configurations locally and understand the impact on performance and log volumes. In this video we compare Change Data Capture (CDC) mechanisms across major enterprise databases including SQL Server, MySQL, Oracle, and PostgreSQL. Nov 27, 2025 · Key Takeaways: PostgreSQL Change Data Capture (CDC) Why CDC matters: CDC ensures that changes (inserts, updates, deletes) in a PostgreSQL database propagate incrementally — avoiding full data reloads and enabling near real-time sync across systems. Jan 30, 2026 · Master Postgres Change Data Capture (CDC) with query, trigger, and log-based methods. This makes it possible to react to data changes in real time, keep systems synchronized, and build event-driven architectures. Compare three approaches: triggers, queries, and logical replication, and their pros and cons. Your nightly full-table extract slams the source Postgres cluster with massive SELECT queries, wastes hours copying millions of rows that haven't changed, and still leaves the warehouse stale until tomorrow morning. Debezium is an open-source CDC platform that supports log-based replication for databases such as PostgreSQL. .
