> Key: SPARK-52448
> URL: https://issues.apache.org/jira/browse/SPARK-52448
> Project: Spark
> Issue Type: Task

> Affects Versions: 4.1.0
> Reporter: Herman van Hövell
> Assignee: Yihong He
> 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 {}}
> {{ repeated StructField fields = 1;}}

> {{message StructField {}}
> {{ string name = 1;}}
> {{ Literal value = 2;}}
> {{ optional boolean nullable = 3;}}
> {{ optional string metadata = 4;}}
> {{}}}
