Chao Sun updated SPARK-33311:
-----------------------------
Parent: SPARK-33507
Issue Type: Sub-task (was: Improvement)
> Improve semantics for REFRESH TABLE
> -----------------------------------
>
> Key: SPARK-33311
> URL: https://issues.apache.org/jira/browse/SPARK-33311
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.0.1
> Reporter: Chao Sun
> Priority: Major
>
> Currently, the semantics for {{REFRESH TABLE t}} is not well defined for view
> (let's say {{view}}) that reference the table {{t}}:
> 1. If {{view}} is cached, the behavior is not well-defined. Should Spark
> invalidate the cache (current behavior) or recache it?
> 2. If {{view}} is a temporary view, currently refreshing {{t}} does not
> refresh {{view}} since it will just reuse the logical plan defined in the
> session catalog. This could lead query failures (although with a helpful
> error message) or to incorrect results depending on the refresh behavior.
> I think we should clear define and document the behavior here, so that users
> won't get confused.
