gRPC
Schema evolution is one of the hardest problems in distributed systems. When a gRPC service and its clients evolve independently — which they always do — a change to a .proto file can silently break production. This guide covers how to test Protocol Buffer schema compatibility before it becomes a production incident.
Testing
Changing a Protobuf schema without breaking consumers is one of the most error-prone tasks in service maintenance. The rules seem simple, but they're easy to violate under deadline pressure. This guide covers which changes are safe, which are breaking, how to test for both, and how to
Protobuf
Protocol Buffers (Protobuf) is not just a serialization format — it's a schema system. When you change a .proto file, you're changing a contract that potentially affects every service that uses it. Testing Protobuf schemas means validating not just that serialization works, but that your changes don&
