James Taylor commented on PHOENIX-4530: --------------------------------------- Thanks for confirming, [~vincentpoon]. Please commit to 4.x, 5.x, and master branches. > Do not collect delete markers during major compaction of table with disabled > mutable indexes > -------------------------------------------------------------------------------------------- > > Key: PHOENIX-4530 > URL: https://issues.apache.org/jira/browse/PHOENIX-4530 > Project: Phoenix > Issue Type: Improvement > Environment: > Reporter: James Taylor > Assignee: Vincent Poon > Priority: Major > Attachments: PHOENIX-4530.master.v1.patch, > PHOENIX-4530.master.v2.patch > > > If major compaction occurs on a table with mutable indexes that have the > INDEX_DISABLE_TIMESTAMP set, we currently permanently disable the index, > forcing it to be manually rebuilt from scratch. This is to prevent it from > potentially being corrupted as we need the delete markers to remain in order > to guarantee the data table and index table remain in sync. > An alternate approach (mentioned by [~an...@apache.org] during review) is to > detect this case in a pre-compaction hook and set the compaction up so that > delete markers are not removed. This would have the advantage that we > wouldn't have to permanently disable the index and rebuild it from scratch. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
