-------------------------------------

             Summary: Support tombstone messages in FLINK's "kafka" connector
                 Key: FLINK-25106
                 URL: https://issues.apache.org/jira/browse/FLINK-25106
             Project: Flink
          Issue Type: Improvement
          Components: API / Core
            Reporter: Varun Yeligar


Currently, FLINK's "kafka" connector ignores all the tombstone messages, whereas the "upsert-kafka" connector supports tombstone messages and sets the type of the row to RowKind.DELETE ([Code Link|https://github.com/apache/flink/blob/master/flink-connectors/flink-connector-kafka/src/main/java/org/apache/flink/streaming/connectors/kafka/table/DynamicKafkaDeserializationSchema.java#L126]).

I wanted to know if it is feasible to support tombstone messages in "kafka" connector by setting all the value fields to NULL and the RowKind to DELETE. I could also raise a PR with the respective changes if required.
