------------------------------------------
I've added a design doc to the description and will start a discussion on the
dev list next.
> SPIP: Stored Procedures API for Catalogs
> ----------------------------------------
>
> Key: SPARK-44167
> URL: https://issues.apache.org/jira/browse/SPARK-44167
> Project: Spark
> Issue Type: New Feature
> Components: SQL
> Affects Versions: 4.0.0
> Reporter: Anton Okolnychyi
> Priority: Major
> Labels: SPIP
>
> Similar to engines like Trino, it would be great to provide a connector API
> for stored procedures and the corresponding CALL statements to invoke them.
> Such extensions are already used by projects like Hudi and Iceberg. Many
> custom Delta operations can be represented in the same way, reducing the
> amount of parser code to maintain.
> Proposal is available
> [here|https://docs.google.com/document/d/1rDcggNl9YNcBECsfgPcoOecHXYZOu29QYFrloo2lPBg].
