  • All Implemented Interfaces:
    org.apache.cassandra.cdc.api.CassandraSource
    public class CassandraClientSource
extends java.lang.Object
implements org.apache.cassandra.cdc.api.CassandraSource
    Optional `CassandraSource` implementation that reads values from the Cassandra cluster using the standard Cassandra client. This is only used for reading unfrozen lists. In Cassandra, unfrozen lists store the list index as a timeuuid which is unintelligible for downstream CDC consumers.
