 ## Overview
 
-The functionality of the connector is based upon [change data capture](https://cassandra.apache.org/doc/latest/operating/cdc.html#enabling-or-disabling-cdc-on-a-table) feature provided by Cassandra since [Cassandra 3.x](https://cassandra.apache.org/doc/3.11.3/operating/cdc.html) where CDC was introduced.

 The database operator must [enable](https://cassandra.apache.org/doc/latest/operating/cdc.html#enabling-or-disabling-cdc-on-a-table) _CDC_ for the table(s) that should be captured by the connector.
 The connector then produces a _change event_ for every row-level insert, update, and delete operation that was published via the _CDC API_, while recording all the change events for each table in a Redis Enterprise Database with a choice of your data structure such as [Hashes](https://redis.io/topics/data-types#hashes).
