[jira] [Commented] (SPARK-23836) Support returning StructType &
MapType in Arrow's "scalar" UDFS (or similar)
[ https://issues.apache.org/jira/browse/SPARK-23836?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16422922#comment-16422922 ]
holdenk commented on SPARK-23836:
---------------------------------
[~hyukjin.kwon] its a good question, that one seems to be more just adding support for them, but we already have support for Struct / Map types its just we don't have it in the Scalar transformation. Personally I'd make them linked JIRAs but not a sub issue. Does that sound reasonable?

> Issue Type: Improvement
> Components: PySpark
> Affects Versions: 2.4.0
> Reporter: holdenk
> Priority: Major

> Currently not all of the supported types can be returned from the scalar pandas UDF type. This means if someone wants to return a struct type doing a map operation right now they either have to do a "junk" groupBy or use the non-vectorized results.
