Subject [jira] [Commented] (HBASE-15368) Add relative window support
Date Wed, 02 Mar 2016 01:41:18 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15368?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15174824#comment-15174824

Dave Latham commented on HBASE-15368:

Writing our multiple files in our TODO list as well, so let us know if you start on that (we'll
do the same).  It will be great for major compaction, though for minor compaction may not
be helpful unless done very carefully due to the seq id correctness requirements (i.e. only
do it if minor compacting all files for a single window, and then only write out 2 files)

Using minTimestamp instead of maxTimestamp will not fix the problem with relative windows,
just shifts it to pulling in new data into the older windows and then HFiles.
