> 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.
