Introduction to OpenTelemetry

What You'll Learn

1. Set up OpenTelemetry in a Go gRPC service by configuring the SDK, tracer provider, and initialization order.
2. Trace gRPC requests with OpenTelemetry Go auto-instrumentation and add spans around application and database call flows.
3. Export traces to stdout for local debugging and to Honeycomb, then inspect and enrich spans with custom attributes.
