      Work Description: lostluck opened a new pull request #14192:
URL: https://github.com/apache/beam/pull/14192


   *  Make map encoding deterministic.
   *  Handle embedded Exported fields in the Row coder.
   *  Translating embedded fields to schemas.
   
   Tests cover all non-error cases.
   
   I'm still working on a cleanup and additional testing for Logical types. There's a bunch of code I need to deduplicate, since the duplication isn't useful, and the tests don't cover as much as desired regarding logical types.

> Schema support is required for advanced cross language features in Beam, and has the opportunity to replace the current default JSON encoding of elements.
> Some quick notes, though a better fleshed out doc with details will be forthcoming:
>  * All base coders should be implemented, and listed as coder capabilities. I think only stringutf8 is missing presently.
>  * Should support fairly arbitrary user types, seamlessly. That is, users should be able to rely on it "just working" if their type is compatible.
>  * Should support schema metadata tagging.
> In particular, one breaking shift in the default will be to explicitly fail pipelines if elements have unexported fields, when no other custom coder has been added. This has been a source of errors/dropped data/keys and a simply warning at construction time won't cut it. However, we could provide a manual "use beam schemas, but ignore unexported fields" registration as a work around.
> Edit: Doc is now at https://s.apache.org/beam-go-schemas
