Hey friends, I would like to start discussion for a very small KIP: https://cwiki.apache.org/confluence/display/KAFKA/KIP-462%3A+Use+local+thread+id+for+KStreams
it is trying to avoid sharing thread-id increment between multiple stream instances configured in one JVM. This is an important fix for static membership<https://cwiki.apache.org/confluence/display/KAFKA/KIP-345%3A+Introduce+static+membership+protocol+to+reduce+consumer+rebalances> to be effective for KStreams in edge case like changing `group.instance.id` throughout restarts due to thread-id interleaving. I will open the vote thread in the main while, since this is a very small fix. Feel free to continue the discussion on this thread, thank you! Boyang
