> This proposal outlines the addition of OpenTelemetry support to Ratis. By instrumenting the full client-side request path, we can empower users and maintainers with the granular data necessary for both long-term performance optimization and proactive daily monitoring.
>  * 1-pager proposal: [https://docs.google.com/document/d/1UKGVqOzkAXqUAJxOz1RHq6fIiO3xqV57eIqi-f9qdE4/edit?tab=t.0#heading=h.5a3u31wlm0n]
>  * PoC: [https://github.com/taklwu/ratis/tree/opentelemetry0129]
> Subtasks
>  * Define the Metadata Field: Modify RaftRpcMessage.proto to include an optional SpanContext field.
>  * Add TraceUtil: Land the utility class in ratis-common based on the code you see in HBase.
>  * Create the client span: Introduce the span supplier and CLIENT span hook.
>  * Instrument GRPC on the Server: Start with the GRPC module as it is the most common transport. Instrument the onNext methods (or within the caller) to start/stop spans.
>  * Come up with the user guide as part of the release.
>  
> Preliminary results were captured by running filestore example.
