Subject [jira] [Commented] (HBASE-15368) Add relative window support
Date Tue, 01 Mar 2016 21:26:18 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15368?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15174432#comment-15174432

Clara Xiong commented on HBASE-15368:
-------------------------------------

+1 on Dave's comments.

I'd like to point out the fixed window strategy takes current time to determine whether to
promote older windows to higher tiers.  Therefore it guarantees most recent data are in the
smallest windows. It also guarantees at least one window remaining on the current tier before
promoting the others to the higher tier.
