> Query with lookup table always use latest snapshot
> --------------------------------------------------
>
> Key: KYLIN-3628
> URL: https://issues.apache.org/jira/browse/KYLIN-3628
> Project: Kylin
> Issue Type: Improvement
> Reporter: Na Zhai
> Assignee: Na Zhai
> Priority: Major
> Fix For: v2.6.0
>
>
> If user queries a lookup table, Kylin will randomly selects a Cube (which has
> the snapshot of this lookup table) to answer it. This causes uncertainty when
> there are multiple cubes (share the same lookup): some cubes are newly built,
> some not. If Kylin picks an old cube, the query result is old.
> To remove this uncertainty, for such queries, either always use latest
> snapshot, or use earlist snapshot. We believe the "latest" version is better.
