Hi @patkivikram, looks great, did you use some linter for the files here? It's really hard to review because of the big amount of changes unrelated to logic. Would it be hard to either do a separate PR if the linter used is "black" or revert the lint changes? Sorry for the trouble.

Hi all, just wondering if this PR has an ETA?

Jan 27 '21 09:01 deed02392

What's left to do to get this merged? Can I help? @tvoinarovskyi - any insights?

Feb 24 '21 13:02 forsberg

Hi, thanks for the work on this, now it's rally clear and I would love to have this merged. The only issue I have is the abscense of tests and I am not familiar with the Static group management enough. Could you share how did you test the change, can you try preparing a test to reproduce the membership change? Or I could try to do it if I know how to reproduce it manually.

Feb 27 '21 17:02 tvoinarovskyi

Here's how I reproduce it manually (which I'm not sure if you can automate...it's a little messy):

Assume a topic with multiple partitions and multiple consumers.
In non-KIP-345-mode
- When one consumer leaves, the other consumers immediately rebalance.
- When the original consumer returns, another rebalance occurs and the original consumer gets partitions that may or may not include its original assignments, depending on the negotiation in the rebalance.
In KIP-345-mode
- When one consumer leaves, no rebalance occurs until after that consumer's session timeout expires.
- If the original consumer rejoins the group before its session timeout expiration, the consumer is assigned the same partitions it had before leaving.

I've tested this manually by running consumers locally and watching what happens when I kill or stop one of them, which I acknowledge is not the greatest way to test something.
