--------------------------------------

             Summary: Old ProduceRequest with zstd compression does not return error to client
                 Key: KAFKA-7549
                 URL: https://issues.apache.org/jira/browse/KAFKA-7549
             Project: Kafka
          Issue Type: Bug
          Components: compression
            Reporter: Magnus Edenhill


Kafka broker v2.1.0rc0.

 

KIP-110 states that:

"Zstd will only be allowed for the bumped produce API. That is, for older version clients(=below KAFKA_2_1_IV0), we return UNSUPPORTED_COMPRESSION_TYPE regardless of the message format."

 

However, sending a ProduceRequest V3 with zstd compression (which is a client side bug) closes the connection with the following exception rather than returning UNSUPPORTED_COMPRESSION_TYPE in the ProduceResponse:
