Github user medcv commented on the issue: https://github.com/apache/flink/pull/6259 @dawidwys Thanks! As far as I dog on Confluent code, their api needs `subject` to retrieve the Schema Id and version and it should be provided by consumer. https://github.com/confluentinc/schema-registry/blob/master/client/src/main/java/io/confluent/kafka/schemaregistry/client/SchemaRegistryClient.java#L30 Purpose of new commit is to address your first comments by removing `topic` name in the serialization constructor and replace it with `subject`. So this way serializer doesn't need to know about the `topic` name. If you still see issues with this approach I would appreciate it if you help me to find a better solution.
