Ismael Juma updated KAFKA-18659:
--------------------------------
Fix Version/s: 4.0.0
> 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
> Priority: Blocker
> Fix For: 4.0.0
>
>
> 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.
