Subject [jira] [Commented] (HBASE-15368) Add relative window support
Date Thu, 03 Mar 2016 02:34:18 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15368?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15177025#comment-15177025
] 

Dave Latham commented on HBASE-15368:
-------------------------------------

Agreed, no need for an abstraction unless we expect an alternate implementation.  I still
think a calendar based alternative would be reasonable if anyone wanted it.  Cassandra's DTCS
also uses fixed windows, not relative ones (see for example the secton "How DTCS works" at
 https://labs.spotify.com/2014/12/18/date-tiered-compaction/ ).
