Ted Yu commented on HBASE-18547: -------------------------------- One potential solution is for cleaner chore to notify BackupLogCleaner which files have been successfully deleted. BackupLogCleaner can respond and clean up related entries in backup table. > Provide better cleanup of WAL related entries in backup table > ------------------------------------------------------------- > > Key: HBASE-18547 > URL: https://issues.apache.org/jira/browse/HBASE-18547 > Project: HBase > Issue Type: Bug > Reporter: Ted Yu > > I was discussing the design around incremental backup with Vladimir. > Currently if WAL file is recorded in backup table, BackupLogCleaner would > signal that the file can be cleaned up. > However, cleaner chore doesn't notify BackupLogCleaner whether the file is > actually deleted. > This means that potentially large number of WAL file entries would stay in > backup table. > This issue is to investigate better cleanup strategy for the WAL entries. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
