Date Thu, 14 Jul 2016 04:07:20 GMT
fengYu created KYLIN-1891:
-----------------------------

             Summary: merge interval support
                 Key: KYLIN-1891
                 URL: https://issues.apache.org/jira/browse/KYLIN-1891
             Project: Kylin
          Issue Type: Improvement
            Reporter: fengYu
            Assignee: fengYu


We always has some data need to be amended some days later

in current kylin, once I set Auto Merge Thresholds, the segment newly build will merge if
reach Thresholds, the next day refresh will refresh merged segemnt, which is unnecessary.

So I want to add a interval configuration means auto merge will merge segments outside of
the interval. 

for example, if interval = 2, Auto Merge Thresholds=7, if 07-01 to 07-07 is built, auto merge
will not trigger, when 07-09 built success, auto merge will trigger and merge segments from
07-01 to 07-07.
