Subject [jira] [Commented] (HBASE-10560) Per cell TTLs
Date Wed, 23 Jul 2014 15:30:41 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10560?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14071860#comment-14071860

Lars Hofhansl commented on HBASE-10560:

bq. We could try moving TTL logic into the delete tracker. Would need to check how the stacking
works after HBASE-10885. 

I think that would be cool. In fact, why not express all the ScanQueryMatcher logic with filters
(that's something that our [~jesse_yates] suggested a long time ago). That would (a) allow
users to easily customize the logic and (b) get rid of a whole bunch of custom framework logic.
Imagine a FilterList and deals with deletes, TTL, MinVersions, etc, each implemented as a
clean, separate filter. How cool would that be?
