> 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
