Ismael Juma created KAFKA-18659: ----------------------------------- Summary: librdkafka compressed produce fails unless api versions returns produce v0 Key: KAFKA-18659 URL: https://issues.apache.org/jira/browse/KAFKA-18659 Project: Kafka Issue Type: Bug Reporter: Ismael Juma Assignee: Ismael Juma
A large percentage of non Java clients are unable to produce compressed records (with lz4, gzip, snappy) to Apache Kafka 4.0 due to a bug in how librdkafka evaluates whether compression is supported - if the api versions response does not include produce v0, compression with these formats is disallowed (zstd checks a newer version of produce). To fix this, there are two options: # Update KIP-896 not to remove produce v0-v2 and KIP-724 not to remove support for producing messages with record format v0-v1. # Update api versions to return produce v0-v2 as supported, but reject requests with such versions with `UnsupportedVersion` error. The second option seems better to me, even though it's not ideal. -- This message was sent by Atlassian Jira (v8.20.10#820010)
