----------------------------------
Hi [~guozhang] I'm new to KS contribution and would like to take a stab at this
issue. Could you give me some pointers to the "closing task" in context?
> Do not wipe state store under EOS when closing-dirty a RESTORING active or
> RUNNING standby task

> 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 continue restoring the task before
> transit to processing ever (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.
