Subject [jira] [Updated] (HBASE-15454) Archive store files older than max age
Date Fri, 15 Apr 2016 12:31:25 GMT

     [ https://issues.apache.org/jira/browse/HBASE-15454?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Duo Zhang updated HBASE-15454:
------------------------------
    Attachment: HBASE-15454-v4.patch

Add ttl check when archiving. And I do not modify shouldPerformMajorCompaction because the
logic is a little different. Archive is kind of minor compaction, so it is not a good idea
to use the same logic as major compaction that issue a minor compaction every time when there
are some expire data. Instead, I only issue a minor compaction when we drop a whole file.

And also check if the archive candidates should be excluded from minor compaction.

> Sometimes the old data is rarely touched but we can not remove it. So archive it to several
big files(by year or something) and use EC to reduce the redundancy.
