[jira] [Created] (KYLIN-1892) merge interval support

fengYu created KYLIN-1892:
-----------------------------

             Summary: merge interval support
                 Key: KYLIN-1892
                 URL: https://issues.apache.org/jira/browse/KYLIN-1892
             Project: Kylin
          Issue Type: Improvement
          Components: Job Engine
    Affects Versions: v1.5.2
            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.
