[jira] [Commented] (LENS-198) Allow timed dimensions of cube to be non-partitioned columns as well

    [ https://issues.apache.org/jira/browse/LENS-198?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14273574#comment-14273574 ]

-----------------------------------

Why not just create partitions based on et?

> Here is a use case:
> Say cube is having timed dimensions as it and et. If queries come on et and no storage partitioned on et, we fail the queries currently. But if there is notion of et=it plus or minus 10 and storage is partitioned on it, the timerange on et can be resolved to it partitions.
> And if et is direct column along with partition mapping, et filter also needs applied along with partition lookup for it.
> The requirement is to accept cube definition with such timed dimensions and resolve corresponding partitions in StorageTableResolver.
