Review comment:
> If we wait for operation timeout period and if it can't get the lock
after the timeout, it will not have any time remaining for next attempts.
Yes. The guarantee is that the operation will fail or success within the
"operation timeout". No remaining time to retry and failed the operation is
acceptable.
> are you suggesting to wait for operation timeout period while trying to
get lock
Yes. Use the operation timeout period when wait for lock, instead of the
scanner timeout now.
> I think we are going back and forth on which timeout to use.
I thought my point is clearly since we start this discussion. I suggested
that use operation timeout instead of scanner timeout. Then you give me a 15
seconds SLA example. Then I checked the code: use operation timeout can meet
your SLA requirements, too. So why not use operation timeout?
