Subject [jira] [Commented] (HBASE-9004) Fix Documentation around Minor compaction and ttl
Date Mon, 20 Jan 2014 06:04:19 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9004?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13876169#comment-13876169
] 

Feng Honghua commented on HBASE-9004:
-------------------------------------

minor compaction *will* delete expired cells, but only those within the input hfiles selected
by the minor compact. the expired cells in other hfiles not selected by compact still exist
in hfiles, but can't be read out by read/scan since ScanQueryMatcher guarantees to filter
them out by TTL rule when processing read/scan, and these expired cells will eventually be
deleted in subsequent compact if their hosting hfiles are selected by that compact.

> Minor compactions should be able to delete KeyValues outside of ttl.  The docs currently
suggest otherwise.  We should bring them in line.
