-------------------------------------
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.
