structs

[Guillaume Masse <ma...@narrative.io.INVALID>]

Hi All,

I created a ticket to implement an Apache Spark function called named_struct
https://issues.apache.org/jira/browse/CALCITE-5701

I'm wondering if there is already a construct for creating nested
structures and their types. I saw an open PR for nested row types:
https://github.com/apache/calcite/pull/2573

any hints on the subject is gratefully received, I'm planning on working on
this task this week.

I added some comments to the Jira case.

Thanks for finding PR 2573 (for https://issues.apache.org/jira/browse/CALCITE-4842). I think that case needs to be fixed first. That PR looks almost ready.

Julian
