--------------------------------------
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:
