These are the protocol buffers definitions corresponding to the Avro schema
proposed in https://s.apache.org/beam-runner-api.
Differences from the schema there:
- Graph structure is decoupled from what data annotations the nodes
- Adopted names from the Fn API's proto for things that overlap
- Added explicit URNs and payloads for primitives
- Added outline of state and timers
- Added Environment URLs
I would like to merge this and separately port the Fn API to use shared
structures as appropriate, since that may involve more extensive coding work.
Unlike #662, this is _not_ a WIP just for discussion. This is intended for
immediate use as the serialization format for various pieces of the pipeline to
unblock work on the Fn API.
