Introduction

SmallRye Fault Tolerance is comprised of the following main artifacts:

  • io.smallrye:smallrye-fault-tolerance-api: public API for the features provided on top of MicroProfile Fault Tolerance;

  • io.smallrye:smallrye-fault-tolerance-core: core implementations of fault tolerance strategies;

  • io.smallrye:smallrye-fault-tolerance: CDI-based implementation of MicroProfile Fault Tolerance.

These artifacts must be always present, together with the following dependencies:

  • Jakarta CDI, Annotations and Interceptors API;

  • org.eclipse.microprofile.fault-tolerance:microprofile-fault-tolerance-api;

  • org.eclipse.microprofile.config:microprofile-config-api and some implementation;

  • org.eclipse.microprofile.metrics:microprofile-metrics-api and some implementation (implementation is only required if fault tolerance metrics are enabled);

  • io.smallrye.reactive:smallrye-reactive-converter-api;

  • org.jboss.logging:jboss-logging.

Some other artifacts are provided to facilitate additional integrations. These are described in the subsequent sections.

Most of the integration is performed automatically by the CDI Portable Extension present in SmallRye Fault Tolerance: io.smallrye.faulttolerance.FaultToleranceExtension. Make sure the extension is active. The remaining integration concerns are described in the following sections:
