Greetings, We have an existing Cassandra cluster (3.0.9) running on production.
Now ,we want to create data pipelines to ingest data from Cassandra and persist in hadoop. We are thinking of using CDC feature (available from Cassandra 3.8) along with Kafka Connect. We are thinking of creating a new read-only DC which will replicate data from the Production DC.This new DC will be running the latest Cassandra version (3.8+) with CDC enabled. Shown in this diagram : https://i.stack.imgur.com/hkGBh.png My questions: 1. For replication to work, do we need both dc's running same version of Cassandra? Can't we achieve this without upgrading the DC used by the service? 2. Is it possible to enable CDC feature only in the new read-only DC?
