> Components: streams
> Reporter: Guozhang Wang
> Priority: Major
>
> Today whenever we are closing-dirty a task, we always wipe out the state
> stores if we are under EOS. But when the closing task was a RESTORING active,
> or a RUNNING standby, we may actually not need to wipe out the stores since
> we know that upon resuming, we would still restore the task before transit to
> processing (assuming the LEO offset would not be truncated), i.e. when they
> resumes it does not matter if the same records gets applied twice during the
> continued restoration.
