PostgreSQL CDC, Evolved: Read-Only Mode, IAM Auth & Partition Support Now in EstuaryEstuary has released significant updates to its PostgreSQL connectors, expanding support for production-grade change data capture (CDC) use cases. What's NewRead-Only CaptureEstuary now supports CDC in read-only mode without needing to write to a watermarks table. Read-only captures should include a table with frequent updates or a "heartbeat" table to ensure WAL retention doesn't grow continuously. Read-only mode also allows capturing from a PostgreSQL standby replica, letting teams offload replication impact from the primary database entirely. Capturing from read-only standbys requires: - PostgreSQL 16 or later - Logical decoding enabled - hot_standby_feedback = on to retain catalog metadata IAM AuthenticationBoth PostgreSQL source and destination connectors now support IAM authentication, enabling role-based access for teams running PostgreSQL on AWS, GCP, or Azure. This removes the need to manage static database credentials in pipeline configurations. Partitioned Table SupportA new advanced setting called "Capture Partitioned Tables as Partitions" allows each partition of a partitioned PostgreSQL table to be captured as an individual stream, giving teams fine-grained control over how partitioned data flows through their pipelines.
