What is Debezium?

Debezium is a change data capture (CDC) tool for capturing CDC change logs from databases related to updates, deletes, and inserts to source tables.  Debezium can access these logs and that information can be used downstream to update CDC changes against copies of the source tables in a different platform system.  Debezium is also open source.  FiveTran is a competitor to Debezium but they charge for the CDC service they offer.
