Provide coprocessor hooks in put flow while rollbackMemstore.
-------------------------------------------------------------
Key: HBASE-5617
URL: https://issues.apache.org/jira/browse/HBASE-5617
Project: HBase
Issue Type: Improvement
Reporter: ramkrishna.s.vasudevan
Assignee: ramkrishna.s.vasudevan
Fix For: 0.96.0
With coprocessors hooks while put happens we have the provision to create new
puts to other tables or regions. These puts can be done with writeToWal as
false.
In 0.94 and above the puts are first written to memstore and then to WAL. If
any failure in the WAL append or sync the memstore is rollbacked.
Now the problem is that if the put that happens in the main flow fails there is
no way to rollback the
puts that happened in the prePut.
We can add coprocessor hooks to like pre/postRoolBackMemStore. Is any one hook
enough here?
