Martijn Visser updated FLINK-25106:
-----------------------------------
Description:
The Flink Kafka connector allows you to specify the specific offsets for each
partition per
https://nightlies.apache.org/flink/flink-docs-stable/docs/connectors/table/kafka/#scan-startup-specific-offsets,
but this is currently not supported for the Upsert Kafka connector.
We should add this capability also to the Upsert Kafka connector.
was:
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]).
The Flink Kafka connector allows you to specify the specific offsets for each
partition
https://nightlies.apache.org/flink/flink-docs-stable/docs/connectors/table/kafka/#scan-startup-specific-offsets,
but this is currently not supported for the Upsert Kafka connector.
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.
