Worklog Id: (was: 87302)
Time Spent: 6h 20m (was: 6h 10m)
> Support schema in PCollections
> ------------------------------
>
> Key: BEAM-3437
> URL: https://issues.apache.org/jira/browse/BEAM-3437
> Project: Beam
> Issue Type: Wish
> Components: beam-model
> Reporter: Jean-Baptiste Onofré
> Assignee: Jean-Baptiste Onofré
> Priority: Major
> Time Spent: 6h 20m
> Remaining Estimate: 0h
>
> 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.
