At work we use the ThreadContextMap in a manner similar to what is shown in Log4j-Audit - We use Filters/Interceptors to inject data into the ThreadContextMap when a request is received/consumed and inject the data as headers on outbound calls or publishing.
We are now looking at integrating some of that data into OpenTracing/Open Telemetry. It seems like there should be a way to automatically handle this with the ThreadContextMap but for the life of me I cannot figure out how. The ThreadContextMap by itself doesn’t support integration with HTTP/Kafka/AMQP, etc without leveraging what is in Log4j-Audit. It somehow feels wrong that we don’t have a way to support this but the solution isn’t obvious to me. Thoughts? Ralph
