Description

The Pull request fixes the connector issue, in which Cassandra CDC (Change Data Capture) Source Connector encounters a ClassCastException when processing data from tables that contain collection columns (list, map, or set) storing timestamp values.

What's added/changed

• Custom Marshalling method for collection fields in AbstractNativeConverter, which checks for Instant type data and converts that to long data.
