Subject [jira] [Commented] (HBASE-14417) Incremental backup and bulk loading
Date Tue, 09 Aug 2016 23:38:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14417?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15414447#comment-15414447
] 

Ted Yu commented on HBASE-14417:
--------------------------------

Discussed with Devaraj.
Quick solution is to detect the presence of bulk loaded hfiles between full backup and incremental
backup. If bulk load is detected, convert incremental backup to full backup.

Better solution, related to HBASE-14141, is to list bulk loaded hfiles during incremental
backup and put them in their own backup image.

> Currently, incremental backup is based on WAL files. Bulk data loading bypasses WALs
for obvious reasons, breaking incremental backups. The only way to continue backups after
bulk loading is to create new full backup of a table. This may not be feasible for customers
who do bulk loading regularly (say, every day).
