Neon has announced the beta release of logical replication, a feature in Postgres that facilitates Change Data Capture (CDC) by allowing real-time data streaming to external data stores. CDC is crucial for maintaining data synchronization, minimizing latency, and supporting event-driven architectures, especially in distributed systems. Logical replication in Postgres uses a publisher-subscriber model, leveraging the Write-Ahead-Log (WAL) to capture and stream data changes selectively, offering flexibility over physical replication. This release supports the `wal2json` format, enabling integration with various data platforms like Materialize or Kafka. However, it does not currently support subscriber capabilities or automatic replication of Data Definition Language (DDL) operations, requiring manual intervention for schema changes. Despite its limitations, logical replication is a pivotal feature for modern applications, and Neon encourages users to explore its potential and contribute feedback.
