David Milicevic resolved SPARK-48377.
-------------------------------------
Resolution: Later
Marking this item as "Later" for a simple reason - too complex for now.
We are in the process of designing and introducing a support for stored
procedures as well. Together with it, we are thinking of introducing a new
concept like Table Reference variable, which will be much easier and intuitive
way to achieve the same/similar as with multiple results API.
Similar is true for cursors, if we decide to introduce the concept sometime in
the future, that might be a better way to handle multiple results.
Until all of those decisions are figured out/made, we cannot make a decision on
this item as well.
> [M3] Multiple results API - sqlScript()
> ---------------------------------------
>
> Key: SPARK-48377
> URL: https://issues.apache.org/jira/browse/SPARK-48377
> Project: Spark
> Issue Type: Sub-task
> Components: Spark Core
> Affects Versions: 4.0.0
> Reporter: David Milicevic
> Priority: Major
>
> For now:
> * Write an API proposal
> ** The API itself should be fine, but we need to figure out what the result
> set should look like, i.e. in what format we return multiple DataFrames.
> ** The result set should be compatible with CALL and EXECUTE IMMEDIATE as
> well.
> * Figure out how the API will propagate down the Spark Connect stack
> (depends on SPARK-48452 investigation)
>
> Probably to be separated into multiple subtasks in the future.
