URL: https://github.com/apache/beam/pull/14773


   Schema UUIDs being random for every instance doesn't work for Go, which relies significantly on a deterministic identifier registry between worker and main program binary.
   
   Make the UUIDs deterministic based on the type name. The schema spec, such as it is only requires that two types with the same UUID are identical, which this method can support.
   
   This is largely an issue when trying to avoid deviations to the reflect libraries to do type conversions, which can tolerate converting a synthetic type to an equivalent specific type.

> 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
