      Work Description: reuvenlax opened a new pull request #4964: [BEAM-3437] Introduce Schema class, and use it in BeamSQL
URL: https://github.com/apache/beam/pull/4964
 
 
   We introduce the new Schema and Row classes. In this pull request, the classes are only used in BeamSQL. This replaces the previous BeamSQL RowType class which was a mapping from field name to coder. Nested arrays and rows are fully supported.
   
   Future PRs will add support for schemas on any PCollection.

> As discussed with some people in the team, it would be great to add schema support in {{PCollections}}. It will allow us:
> 1. To expect some data type in {{PTransforms}}
> 2. Improve some runners with additional features (I'm thinking about Spark runner with data frames for instance).
> A technical draft document has been created: 
> https://docs.google.com/document/d/1tnG2DPHZYbsomvihIpXruUmQ12pHGK0QIvXS1FOTgRc/edit?disco=AAAABhykQIs&ts=5a203b46&usp=comment_email_document
> I also started a PoC on a branch, I will update this Jira with a "discussion" PR.
