> Support offset for segment merge
> --------------------------------

> Key: KYLIN-3141
> URL: https://issues.apache.org/jira/browse/KYLIN-3141
> Project: Kylin
> Issue Type: New Feature
> Components: Job Engine
> Reporter: Wang, Gang
> Assignee: Wang, Gang
> Priority: Minor
>
> This is a request to add an offset to the Kylin segment merge so as to avoid
> immediate merge of segments after a 7 day / 30 day window.
> Introducing a delay(offset) would help in 2 things -
> a) When auto merge kicks off I have a new segment and my daily incremental
> segment build script will fail because they won’t find the last segment.
> b) Lot of use cases where I may need to do data backfills for some of the
> days of the previous week, but I end up refreshing the whole merged segment
> instead of a day or two.
