Debezium Review

Should I use Debezium?

Open source distributed platform for change data capture (CDC). - debezium.io

· 1 month ago

The de facto free standard for CDC if you already run Kafka and have engineers to own the ops. Skip it if you want a managed, low-ops pipeline — buy a hosted CDC tool instead.
