> 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: 
> I also started a PoC on a branch, I will update this Jira with a "discussion" PR.
