> REFRESH TABLE should recreate cache with same cache name and storage level
> --------------------------------------------------------------------------
>
> Key: SPARK-27248
> URL: https://issues.apache.org/jira/browse/SPARK-27248
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: William Wong
> Priority: Major
>
> If we refresh a cached table, the table cache will be first uncached and then
> recache (lazily). Currently, the logic is embedded in
> CatalogImpl.refreshTable method.
> The current implementation does not preserve the cache name and storage
> level. As a result, cache name and cache level could be changed after a
> REFERSH. IMHO, it is not what a user would expect.
> I would like to fix this behavior by first save the cache name and storage
> level for recaching the table.
