Robert Metzger updated FLINK-20379:
-----------------------------------
Priority: Critical (was: Blocker)
> New Kafka Connector does not support DeserializationSchema
> ----------------------------------------------------------
>
> Key: FLINK-20379
> URL: https://issues.apache.org/jira/browse/FLINK-20379
> Project: Flink
> Issue Type: Bug
> Components: Connectors / Kafka
> Reporter: Stephan Ewen
> Priority: Critical
> Fix For: 1.12.0
>
>
> 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.
