hongbin ma commented on KYLIN-1892:
-----------------------------------

This is exactly I want, I called it "volatile periods". Auto merging will never attempt to merge segments in "volatile periods". are you interested in committing a patch?

> 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.
