> After HBASE-3787, we could store mvcc in operation context, and use it to convert the
modification request into read on dups instead of throwing OperationConflictException.
> MVCC tracking will have to be aware of such MVCC numbers present. Given that scanners
are usually relatively short-lived, that would prevent low watermark from advancing for quite
a bit more time
