Package dev.restate.sdk.interceptor.micrometer

Class MicrometerInterceptorFactory

java.lang.Object

dev.restate.sdk.interceptor.micrometer.MicrometerInterceptorFactory

All Implemented Interfaces:

HandlerInterceptor.Factory, RunInterceptor.Factory

public final class MicrometerInterceptorFactory
extends Object
implements HandlerInterceptor.Factory, RunInterceptor.Factory

Micrometer Observation interceptor factory for Java handlers. Implements both HandlerInterceptor.Factory and RunInterceptor.Factory so a single registration covers both invocation- and run-level observations.

Spans produced through the Micrometer → tracing bridge mirror those emitted by sdk-interceptor-opentelemetry: attempt <target> for the handler and run (<name>) for each ctx.run, with restate.invocation.id, restate.invocation.target, and restate.run.name attributes.

Observation scope is thread-local. Use with MicrometerRunContextPropagator (registered via SPI by default) to propagate spans to run closures.

Method Details

createHandlerInterceptor

public @Nullable HandlerInterceptor createHandlerInterceptor()

Description copied from interface: HandlerInterceptor.Factory

Create HandlerInterceptor. Invoked once at endpoint initialization, hence the resulting interceptor is cached and reused across all invocations.

Return null to skip this factory.

Specified by:

createHandlerInterceptor in interface HandlerInterceptor.Factory

createRunInterceptor

public @Nullable RunInterceptor createRunInterceptor()

Description copied from interface: RunInterceptor.Factory

Create RunInterceptor. Invoked once at endpoint initialization, hence the resulting interceptor is cached and reused across all invocations.

Return null to skip this factory.

Specified by:

createRunInterceptor in interface RunInterceptor.Factory
