Lars Hofhansl commented on HBASE-5199: -------------------------------------- Need to pay some special attention to specific delete-marker TTL that FB added (i.e. a delete marker could outlive the TTL of a store). Can't find the jira for that right, but it was committed relatively recently. > Delete out of TTL store files before compaction selection > --------------------------------------------------------- > > Key: HBASE-5199 > URL: https://issues.apache.org/jira/browse/HBASE-5199 > Project: HBase > Issue Type: Improvement > Reporter: Liyin Tang > Assignee: Liyin Tang > > Currently, HBase deletes the out of TTL store files after major compaction. > We can change the sequence to delete the out of TTL store files before > selecting store files for compactions. > In this way, HBase can keep deleting the old invalid store files without > major compaction, and also prevent from unnecessary major compactions since > the out of TTL store files will be deleted before the compaction selection. -- This message is automatically generated by JIRA.
