grpc_dynamic_codegen

Overview

Our service takes in a payload containing bytes and capitalizes them.

Using OpenTelemetry gRPC Instrumentation, we can collect traces of our system and export them to the backend of our choice (we can use Zipkin or Jaeger for this example), to give observability to our distributed systems.

This is the dynamic code generation variant of the gRPC examples. Code in these examples is generated at runtime using Protobuf.js.
