OTLP Receiver to OTLP Exporter: Does the OpenTelemetry Collector preserve incoming W3C tracestate entries unchanged?
The goal is to confirm whether an OpenTelemetry Collector, when receiving spans through an OTLP receiver from an SDK‑instrumented service, forwards the original W3C traceparent and tracestate headers unchanged via its OTLP exporter to a downstream backend. This concerns the preservation of trace context across the Collector boundary. The OTLP specification d
