Hi @dao-jun , I see that you are also a member of OpenTelemetry, have you also considered contributions to the opentelemetry-java-instrumentation ? I don't see any instrumentation module for apache pulsar in instrumentation so that would be a useful contribution there. Also, we are currently focusing on opentelemetry so that would make any contribution more future-proof and also bring it to more users.

I am not familiar with Apache Pulsar though, but we can help you craft an instrumentation for it if needed.

@SylvainJuge Hi, thanks for your reply, I contributed Pulsar instrumentation to OpenTelemetry java instrumentation years agohere.
