34. What is CDI Lite? Providing a lighter CDI footprint (CPU, memory, runtime size) Constrained environment Cloud environnement Main goal : providing a CDI subset able to provide the CDI magic at build time First candidates for this Lite approach Quarkus Micronaut Helidon
35. What’s not in CDI Lite Decorators (could be done, but the effort is bigger than the usage) @Session and @Conversation scopes Specialization than requires a lot of re fl ection Beans Passivation The standard Portable extension but we provided a new build time compatible extension! Good news: as full is a lite super set, features could be moved to Lite later
36. Build time compatible extension Most of the feature provided by portable extension are also available in build time compatible CDI Full support build time compatible extension You can’t use both in your dev As these extension are activated at build time, a new metadata API was introduced to replace what is done by re fl ection in full
37. Build compatible extension example (enhancement) public class MyExtension implements BuildCompatibleExtension { @Enhancement(types = MyFooService.class) public void foo(ClassConfig clazz) { clazz.removeAnnotation(it -> it.name().equals(MyQualifier.class.getName())); } @Enhancement(types = MyBarService.class) public void bar(ClassConfig clazz) { clazz.addAnnotation(MyQualifier.class); } }
38. Build compatible extension example (synthesis) 1/2 // 2. bean creation function public class MyPojoCreator implements SyntheticBeanCreator<MyPojo> { @Override public MyPojo create(Instance<Object> lookup, Parameters params) { String name = params.get("name", String.class); return new MyPojo("Hello " + name); } } // 3. bean disposal function public static class MyPojoDisposer implements SyntheticBeanDisposer<MyPojo> { @Override public void dispose(MyPojo instance, Instance<Object> lookup, Parameters params) { System.out.println("disposing " + instance.data); } }
39. Build compatible extension example (synthesis) 2/2 // 3. Extension public static class MyExtension implements BuildCompatibleExtension { @Synthesis public void synthesise(SyntheticComponents syn) { syn.addBean(MyPojo.class) .type(MyPojo.class) .withParam("name", "World") .createWith(MyPojoCreator.class) .disposeWith(MyPojoDisposer.class); }

55. Fault Tolerance Spec example 1
56. Fault Tolerance Doc An easy-to-use and fl exible system for building resilient applications
57. Fault Tolerance annotations 1/2 @Asynchronous: to transform a standard method in an asynchronous task. You can control the outcome by having the method returning a Futur @Timeout: to de fi ne a timeout duration on a given task (can be used on a method in the local thread or on an @Asynchronous task). @Retry: To retry an unsuccessful treatment a given number of time
58. Fault Tolerance annotations 2/2 @Fallback: launch an alternative process if the annotated method fails with a given exceptions set @CircuitBreaker: Implementation of the Circuit Breaker pattern (stop calling an unresponsive service, and strategy to reopen the circuit under the hood) @BulkHead: Limit the number a thread using given method and optionally de fi ne a writing queue

62. Three Flavor of check @Liveness: is the service alive? @Startup: is the service already started (may not be ready)? @Readiness: is the service ready to serve request?
