Class EventSourcingTracingConfigurationEnhancer

java.lang.Object

org.axonframework.eventsourcing.tracing.configuration.EventSourcingTracingConfigurationEnhancer

All Implemented Interfaces:

ConfigurationEnhancer

@Internal
@RegistrationScope("Register decorators once at the root; do not re-invoke in child module registries (the DecoratorDefinitions are copied down and reach module-built components on their own). Re-invoking per nesting level re-registers the decorators and produces duplicate nested spans.")
public final class EventSourcingTracingConfigurationEnhancer
extends Object
implements ConfigurationEnhancer

ConfigurationEnhancer that wires tracing into axon-eventsourcing components. Discovered automatically via ServiceLoader, so dropping the axon-eventsourcing module on the classpath is enough.

A component is only decorated when a non-no-op SpanFactory is configured and the corresponding toggle in EventSourcingTracingSettings is enabled.

Since:

5.3.0

Field Details

TRACING_DECORATOR_ORDER

public static final int TRACING_DECORATOR_ORDER

Decorator order for the event-sourcing tracing decorators. Near-maximal so tracing is applied last and is the outermost wrapper - spans cover all inner decorators, and tracing wrappers are reliably detectable by an outermost instanceof check. Same value and rationale as MessagingTracingConfigurationEnhancer.TRACING_DECORATOR_ORDER.

Method Details

enhance

public void enhance(ComponentRegistry registry)

Description copied from interface: ConfigurationEnhancer

Enhances the given registry with, for example, additional components and decorators.

Specified by:

enhance in interface ConfigurationEnhancer

Parameters:

registry - The registry instance to enhance.

order

public int order()

Description copied from interface: ConfigurationEnhancer

Returns the relative order this enhancer should be invoked in, compared to other instances.

Use lower (negative) values for enhancers providing sensible defaults, and higher values for enhancers that should be able to override values potentially previously set. Defaults to 0 when not set.

Specified by:

order in interface ConfigurationEnhancer

Returns:

The order in which this enhancer should be invoked.
