Labels: pull-request-available (was: )
> Add simplified Struct Expression.Literal
> ----------------------------------------
>
> Key: SPARK-52448
> URL: https://issues.apache.org/jira/browse/SPARK-52448
> Project: Spark
> Issue Type: Task
> Components: Connect, SQL
> Affects Versions: 4.1.0
> Reporter: Herman van Hövell
> Priority: Major
> Labels: pull-request-available
>
> The current Expression.Struct literal is somewhat overcomplicated since it
> duplicates most of the information its fields already have. This is bulky to
> send over the wire, and it can be ambiguous.
>
> {{message SimpleStruct {}}
