------------------------------
Sounds it calls for a "refresh" from streaming source.
> Treatment of empty mini-cubes

> Key: KYLIN-925
> URL: https://issues.apache.org/jira/browse/KYLIN-925
> Project: Kylin
> Issue Type: Improvement
> Affects Versions: v2.0
> Reporter: hongbin ma
> Assignee: hongbin ma
>
> Consider the case where streaming's input queue stopped for a while, and
> Kylin streaming builds empty segments out of it. Later the input queue's
> issue was fixed however Kylin streaming will never look back to it.
> It issue gets worse when the empty segments are later merged with other
> non-empty segments. After merging, we'll have no clue that empty segments
> ever existed.
