Consumer fails when consuming messages compressed with ZSTD at the broker level

[DeLaboreMercurio]

Describe the bug When consuming messages from a broker where compression has been set at the broker level with ZSTD compression, the Consumer fails with an UnknownError. This does not happen when ZSTD is set at a producer level instead. This behaviour is observed both in the latest pypi release, as well as in the latest version from the master branch in this repository

Expected behaviour Consumer should be able to consume messages with ZSTD compression, when its set at a broker level, just the same as when its set at a producer level.

Environment (please complete the following information):

• aiokafka version: 0.7.2
• kafka-python version: 2.0.2

Reproducible example When setting up the Broker, add to the server.properties file

compression.type=zstd

On the contrary, when if compression.type is omitted in the server.properties file and instead you create a producer with zstd compression, it works fine.

Have you tried with code from master branch? It should have been fixed in https://github.com/aio-libs/aiokafka/pull/801

[SebasYanik]

Yes, its happening with the latest version from the master branch. Just reconfirmed it. Here's the full log output.

Do we have an update on this?

[bigEvilBanana]

Hey guys! I'm just joining the club with the same issue. Any updates?

[theultimate1]

Is anyone else working on this because I am trying to integrate this into faust but if it's not added here. I will work on first adding support here and then integrating it into faust later

[theultimate1]

Hey, so the zstd error comes because of a fetch request versioning error. Kafka python and by extension this package sends fetch request version 4 and ZSTD support requires version 10 at least. this requires the need for fetch sessions,removed_topics and log_start_offset,current_leader_epoch to be added to the fetch request. I already tested to see if this issue becomes resolved when upgrading the version with default values for those parameters. It does work. I plan to add these features to kafka-python to put into a pull request asap. However, in aiokafka's case I just wanted to check in to see if fetch sessions will interfere the asynchronous nature of this module. this KIP has information on fetch sessions. I plan to see for myself if it will interfere anyway but it would be much more efficient if someone can do the check for me.

Did you specify extra when installing aiokafka? Either aiokafka[zstd] of aiokafka[all] should be used to support ZStandard codec.

@theultimate1 I hit the same problem. Your approach to update Fetch to v10 is spot on. Wondering if you could find time to make a PR soon? Many thanks!

[theultimate1]

I will try to get some actual work done for this. been busy lol. This is definitely on my todo.

[davidvanwyk]

@theultimate1 - if I can lend a hand let me know (but you'll need to brief me on what needs doing/what you've discovered). This is currently a slight blocker for ideal operation on my side.

[theultimate1]

yup I am cleaning up right now. will put in a PR by this week
