Phabricator updated HBASE-5274:
-------------------------------

    Attachment: D1473.1.patch

mbautin requested code review of "[jira] [HBASE-5274] Filter out expired scanners on compaction as well".
Reviewers: Liyin, JIRA, lhofhansl, Kannan

  This is a followup for D1017 to make it similar to D909 (89-fb). The fix for 89-fb used the TTL-based scanner filtering logic on both normal scanners and compactions, while the trunk fix D1017 did not. This is just the delta between the two diffs that brings filtering expired store files on compaction to trunk.

> During the compaction time, HBase will generate a store scanner which will scan a list of store files. And it would be more efficient to filer out the expired store file since there is no need to read any key values from these store files.
> This optimization has been already implemented on 89-fb and this is the building block for HBASE-5199 as well. It is supposed to be no-ops to compact the expired store files.
