> when ignoreZkOffsets set true and startOffsetTime =
> kafka.api.OffsetRequest.EarliestTime().
> workers running -> topology shutdown by user and restart -> workers will read
> from earliest time again
> workers running -> one of workers shutdown by accident and supervisor restart
> the worker -> what offset will the restarted worker read from?
