Sergey Shelukhin created HBASE-9899:
---------------------------------------
Summary: for idempotent operation dups, return the result instead
of throwing conflict exception
Key: HBASE-9899
URL: https://issues.apache.org/jira/browse/HBASE-9899
Project: HBase
Issue Type: Improvement
Reporter: Sergey Shelukhin
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
