Martijn Visser commented on FLINK-25106:
----------------------------------------
[~varunyeligar] Thanks for clarifying. If I understand correctly, you want to
use the Kafka messages in an upsert fashion (so that you can do both updates
and deletes).
I think that the feature need is actually an extension on the upsert-kafka
connector (to support specific offsets), because the key difference there is
between the kafka connector and the upsert-kafka connector is how tombstones
are dealt with currently.
> 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
> Priority: Minor
>
> 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.
