Class MetadataContextSetter

java.lang.Object

org.axonframework.extension.tracing.opentelemetry.MetadataContextSetter

All Implemented Interfaces:

io.opentelemetry.context.propagation.TextMapSetter<Map<String,String>>

public class MetadataContextSetter
extends Object
implements io.opentelemetry.context.propagation.TextMapSetter<Map<String,String>>

This TextMapSetter implementation is able to insert the current OpenTelemetry span context into a Message. However, since a Message is immutable, this injector injects it into the provided Map. It's the responsibility the implementing OpenTelemetrySpanFactory to mutate the message through OpenTelemetrySpanFactory.propagateContext(Message).

The trace becomes the message's parent span in itsMetadata.

Since:

4.6.0
