CDC Pipelines

Unlocking data from the database jail. Change Data Capture (CDC) turns static tables into dynamic streams of events.

Beyond Polling

Traditional ETL jobs run nightly. In a modern business, yesterday's data is too late. We shouldn't be polling the database (`SELECT * FROM orders WHERE updated_at > last_run`); we should be reacting to changes instantly.

CDC tools hook directly into the database's write-ahead log (WAL). Every insert, update, and delete is captured immediately and pushed to a message broker with zero impact on query performance.

Use Cases

  • Cache Invalidation: Instantly update Redis when the primary Postgres record changes.
  • Search Indexing: Keep ElasticSearch/OpenSearch perfectly in sync with your transactional DB.
  • Microservices Sync: Allow other services to subscribe to Order Updates without coupling them to the Orders service API.
