Any idea how much time you will need Mickael?

Personally, I would like to move fast, and delaying the release for an uncertain amount of time seems not desirable. We will do a 4.1.2 release for sure some time later.

But I understand that it's a critical issue for Connect, so I agree that it would be great to get into 4.1.1. (Or as a last resort, so a quick 4.1.2 after you figured out a fix, in case you need more time...)


@Lianet: Thanks for volunteering to be the RM! Can you prepare a release plan?

Hi,

If we do a 4.1.1 I'd like to include

I'm still investigating but it looks like KIP-891 broke plugin
isolation in Connect and thus workloads that worked with Connect 4.0.0
don't work anymore on 4.1.0.

Thanks,
Mickael

Hello,

Agree with the proposed 4.1.1 bug fix release to ship this asap. If we all
agree on the need for it, I would like to volunteer to be the release
manager.

Best,
Lianet

Hello,

we now understand the recently reported memory leak bug in Kafka Streams
4.1.0, and have a PR to fix it.

https://issues.apache.org/jira/browse/KAFKA-19748

I consider this bug severe, as we expect that it affects a large number
of Kafka Streams user, makes Kafka Streams unusable, and there is no
workaround.

So I would like to propose to start 4.1.1 bug-fix release immediately,
and also update the Kafka web page with a note that people should be
careful and maybe not even upgrade to Kafka Streams 4.1.0.

Looking forward to your feedback.
