Colt McNealy commented on KAFKA-13501:
--------------------------------------

Matthias—the description makes sense, your comment is in line with what I 
thought. I just saw the label `new-streams-runtime-should-fix` which was 
related to the State Updater (it seemed _plausible_ that the State Updater 
could have fixed this so I thought it wasn't in error).

On a separate note, how can I reproduce this error? Can I do it by forcing a 
`RecordTooLargeException` or something like that? I'd like to verify this 
behavior and potentially look into a fix; we haven't detected this yet in our 
chaos tests but I would prefer that we catch it rather than our customers.

> There are certain scenario in which Kafka Streams wipes out local state and 
> rebuilt it from scratch. This is a thread local cleanup, ie, no rebalance is 
> triggered, and we end up with an offline task until state restoration 
> finished.
> If standby tasks are enable, it might actually make sense to trigger a 
> rebalance instead, to get the task re-assigned to the instance hosting the 
> standby so get the task active again quickly.
