Review Comment:
> I am sure it is correct, because I tested it.
What exactly did you test? Where are the tests?
I mean that RW transaction has both startTimestamp and corresponding
operations timestamps. Why we use MIN_VALUE for RW instead of actual RW related
timestamps?
> because it gives a guarantee that this request don't wait for safe time.
Could you please share a code, where we wait for a safeTime for the
writeIntent resolution?
