Andrew Purtell commented on HBASE-12975: ---------------------------------------- bq. You mean start HBase 1.+ support for Phoenix 5.0, right? Just to be precise, the suggestion is to support HBase 1.1 and higher with Phoenix 5.0, but not HBase 1.0 or lower. Phoenix 4.x would continue to support 0.98. There'd be a gap, nothing for HBase 1.0.x. We'd work on the timing so HBase 1.1 is released before Phoenix 5.0. Alternatively, Phoenix could major -dot-minor to HBase starting at 5, so: - Phoenix 5.0.x -> HBase 1.0.x - Phoenix 5.1.x -> HBase 1.1.x - Phoenix 6.x.x -> HBase 2.x.x For Phoenix 5.0.x you could continue the implementation strategies used for 0.98 since there wouldn't be alternatives yet. For Phoenix x.y.z where x >= 5 and y > 0 there would be supportable interfaces for SplitTransaction, RegionMergeTransaction (and a supported 'Region' substitute for HRegion (HBASE-12972)) > SplitTranaction, RegionMergeTransaction to should have InterfaceAudience of > LimitedPrivate(Coproc,Phoenix) > ---------------------------------------------------------------------------------------------------------- > > Key: HBASE-12975 > URL: https://issues.apache.org/jira/browse/HBASE-12975 > Project: HBase > Issue Type: Improvement > Reporter: Rajeshbabu Chintaguntla > Assignee: Rajeshbabu Chintaguntla > Fix For: 2.0.0, 1.0.1, 1.1.0 > > Attachments: HBASE-12975.patch > > > Making SplitTransaction, RegionMergeTransaction limited private is required > to support local indexing feature in Phoenix to ensure regions colocation. > We can ensure region split, regions merge in the coprocessors in few method > calls without touching internals like creating zk's, file layout changes or > assignments. > 1) stepsBeforePONR, stepsAfterPONR we can ensure split. > 2) meta entries can pass through coprocessors to atomically update with the > normal split/merge. > 3) rollback on failure. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
