Explore how the MicroProfile Bulkhead policy from the Fault Tolerance feature limits requests and prevents faults from stopping an entire system.
You will learn about the limitations of single-threaded programs by looking at a simple online banking microservice. You'll then implement concurrency to scale your microservice and see how it fails when no fault tolerance is implemented. Next, you'll enable the MicroProfile Fault Tolerance feature and use the Bulkhead policy to prevent the failing method from taking down the whole application. You'll explore the two approaches to Bulkhead, semaphore isolation and thread pool isolation, and the parameters used for the annotation. Finally, you'll add a fallback class, which is invoked if a BulkheadException is thrown.
