The Universal Dataplane API (UDPA): Envoy's Next Generation APIs
summary
Envoy evolves xDS from a tangled v2 surface to a yearly API clock cadence where three major versions are supported and older ones are removed, using protobuf plugins and clang tooling to automate massive mechanical renames; v3 alpha is in development for end-of-year release while v4 targets end of 2020. The codebase already spans 15,000 lines of proto and an ecosystem of order a hundred management servers. A CNCF UDPA Working Group forms to generalize xDS into a standard with compliance tests and a reference implementation.
