Subject [jira] [Commented] (HBASE-14141) HBase Backup/Restore Phase 3: Filter WALs on backup to include only edits from backup tables
Date Thu, 10 Nov 2016 21:30:58 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14141?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15655207#comment-15655207

Vladimir Rodionov commented on HBASE-14141:
-------------------------------------------

Why are we complicating the design with two different modes, and switching and everything.
How will any user chose which one to use? I think we should stick to a single mode / solution
that will work for most of the cases rather than complicating the life of the user and also
maintaining the backup code for two different code paths.

We introduce non-default mode for those customers who wants to save some bytes in a backup
remote storage. This mode is not default one and must be activated explicitly.

The pro- of this approach - it does not require *significant* code change (read my first post).
I do not think that adding additional system switch (mode) complicates life of end user.
There will be no two different code paths for these modes - just one.
