Zhihong Yu commented on HBASE-3584: ----------------------------------- How about we always instantiate WALEdit, called localWalEdit. We have the passedWalEdit. And we maintain effectiveWalEdit which would be: {code} passedWalEdit == null ? localWalEdit : passedWalEdit {code} We use localWalEdit for coprocessor hook and effectiveWalEdit for addFamilyMapToWALEdit() and log.append() :-) > We need to atomically put/delete/increment in one call > ------------------------------------------------------ > > Key: HBASE-3584 > URL: https://issues.apache.org/jira/browse/HBASE-3584 > Project: HBase > Issue Type: Bug > Components: client, coprocessors, regionserver > Reporter: ryan rawson > Assignee: Lars Hofhansl > Fix For: 0.94.0 > > Attachments: 3584-v1.txt, 3584-v3.txt > > > Right now we have the following calls: > put(Put) > delete(Delete) > increment(Increments) > But we cannot combine all of the above in a single call, complete with a > single row lock. It would be nice to do that. > It would also allow us to do a CAS where we could do a put/increment if the > check succeeded. -- This message is automatically generated by JIRA.
