> ----------------------------------------------------------------------------------------
>
> Key: SPARK-41670
> URL: https://issues.apache.org/jira/browse/SPARK-41670
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 3.4.0
> Reporter: Serge Rielau
> Priority: Major
>
> Spark today allows overloading between persisted relations and function and temporary relations and functions.
> It also allows overloading between persisted functions and builtin functions.
> While Spark allows us to disambiguate a persisted objects by qualifying it, there is no qualifier for temp or builtin objects.
> Here we propose to use `builtin` for builtin objects and `session` for session temporary objects.
> If there is a conflict with persisted schemas of this name we can further declare that the catalog for both is `system`
