Definitions

  1. Change Data Capture — a pattern for tracking and propagating changes made to a database by tailing its transaction log rather than polling for differences. CDC enables real-time data pipelines, event-driven microservices, and cache invalidation without modifying application code. Debezium reading PostgreSQL WAL is the canonical modern implementation.

    In plain English: A way to watch a database for changes in real-time by reading its internal log, then sending those changes to other systems automatically.

    Example: We set up CDC with Debezium to stream every database change to Kafka, so the search index and analytics warehouse stay in sync in near real-time.
