Distributed Tracing Integration with OpenTelemetry and Knative _ _ _
summary
Demo shows a Quarkus Java REST app deployed to OpenShift/Knative that scales to zero and back while OpenTelemetry captures traces without changing app code. The stack uses OpenTelemetry Collector to Jaeger as the exporter, Quarkus-generated KService YAML, and a Postgres backend; default Knative idle timeout (~30s) causes scale-to-zero then immediate cold-start on request. Traces for each request appear in Jaeger and new service instances are auto-detected, proving end-to-end serverless tracing works.
