------------------------------
Summary: 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 files would stay in backup
table.
This issue is to investigate better cleanup strategy for the WAL entries.
