Thanks for you interest in contribution to Kafka.
For "streams" in particular, here are few tickets you could pick up:
- https://issues.apache.org/jira/browse/KAFKA-20922
- https://issues.apache.org/jira/browse/KAFKA-20776 (it's assigned to
Jess, but I am not sure if she will be able to pick it up -- if you find
this ticket interesting, just leave a comment and ask about it)
- https://issues.apache.org/jira/browse/KAFKA-20508 (similar to above;
while the ticket is assigned, there was no activity, so I think we could
re-assign)
- https://issues.apache.org/jira/browse/KAFKA-19657 (same)
- https://issues.apache.org/jira/browse/KAFKA-5676
- https://issues.apache.org/jira/browse/KAFKA-6621
- https://issues.apache.org/jira/browse/KAFKA-7380
Just a heads up: we are really struggling to keep up with PR reviews, so
you will need some patients...

Hi Matthias,
Thank you for looking into this, I did go over KIP-1071 and I do feel that
I would be duplicating the work once it is done. I was looking into issues
for new contributors and landed on that one seeing it marked as "code
cleanup". I hope you could steer me in the right direction for new
contributions perhaps over to some specific module.
Meanwhile, I am looking over issues under the labelled "newbie" to work on.
Best Regards,
Naveen

Naveen,
thanks for your interest. Nothing is blocking these tickets. However, I
am wondering if it's worth doing this work? With KIP-1071, we are moving
from client side to broker side assignment, so we will delete the
corresponding client side code eventually.
To be fair: KIP-1071 is not completed yet, and there is also no timeline
when we would remove "classic"; and most likely, it will only be in AK
6.0 release, so many years out.
Nevertheless, it feels a little bit like busy work?

Hi Kafka Community,
While going through Kip's that are completed, I came across the umbrella
issue KAFKA-16868 <https://issues.apache.org/jira/browse/KAFKA-16868>
for code cleanup for KIP-924
<
https://cwiki.apache.org/confluence/spaces/KAFKA/pages/255071551/KIP-924+customizable+task+assignment+for+Streams#KIP924:customizabletaskassignmentforStreams-TaskAssignor
,
what I wanted to know is if these are currently being worked on? or are
there any blockers that I need to be aware of?
Specifically issue KAFKA-16873
<https://issues.apache.org/jira/browse/KAFKA-16873> to
remove INTERNAL_TASK_ASSIGNOR_CLASS config. My plan was to deprecate this
config first then remove it later on, since the related new task assignor
is already present as part of KIP-924.
Let me know your thoughts.
Best Regards,
Naveen
