---------------------------------------

[~apurva], [~ijuma], [~hachikuji] Is this the same as KAFKA-6635? I have a wip solution on that but I'd be happy to receive some feedback if I'm going towards the right direction.

> We should wait at least as long as the timeout for a transaction which has begun completion (commit or abort) to be finished. Tricky thing is whether we should abort a transaction which is in progress. It seems reasonable since that's the coordinator will either timeout and abort the transaction or the next producer using the same transactionalId will fence the producer and abort the transaction. In any case, the transaction will be aborted, so perhaps we should do it proactively.
