All Implemented Interfaces:

ConfigurationEnhancer

@Internal
@RegistrationScope("Contribute the providers once at the root; do not re-invoke in child module registries. The registry decorator is copied down on its own - re-invoking per nesting level would register the same providers multiple times, duplicating span attributes.")
public final class EventSourcingSpanAttributesProviderConfigurationEnhancer
extends Object
implements ConfigurationEnhancer

ConfigurationEnhancer contributing the built-in event-sourcing SpanAttributesProviders to the SpanAttributesProviderRegistry. Discovered automatically via ServiceLoader.

The EventTagsSpanAttributesProvider requires a TagResolver - a framework-registered component - so it is only contributed when one is present in the configuration. Contribution is a decorator on the registry component, so both the EventSourcingTracingSettings.spanAttributesProviders() toggle and the TagResolver presence are evaluated when the registry is resolved - right before the SpanFactory consuming it is constructed, once all component registrations are known.

Since:

5.3.0
