Jiangjie Qin commented on FLINK-20379:
--------------------------------------
[~dwysakowicz] The issue has been fixed in the master branch as well as 1.13. I
left the ticket open because it has not been backported to 1.12 yet. Since it
is an API change to release 1.12, we will need a public discussion before doing
that. There are a few other tickets that needs to be backported as well. I'll
send a discussion email to the mailing list.

> Project: Flink
> Issue Type: Bug
> Components: Connectors / Kafka

> The new Kafka Connector defines its own deserialization schema and is
> incompatible with the existing library of deserializers.
> That means that users cannot use all of Flink's Formats (Avro, JSON, Csv,
> Protobuf, Confluent Schema Registry, ...) with the new Kafka Connector.
> I think we should change the new Kafka Connector to use the existing
> Deserialization classes, so all formats can be used, and users can reuse
> their deserializer implementations.
> It would also be good to use the existing KafkaDeserializationSchema.
> Otherwise all users need to migrate their sources again.
