Feign client with Hystrix throwing exception
I have requirement to call a service multiple times (>50 times) and aggregate the responses. So I have decided to go for CompletableFuture
with Async and CustomExecuter (its own threadpool) to make it faster instead of waiting for the service to respond.
I am using feign client with ApacheHTTP and Hystrix on the classpath. I can see it is working sometimes and sometimes I am getting exceptions as the circuit is open.
Can somebody tell me if it is a correct approach to make parallel calls to service or shall I go with sequential like calling the service in loop? Keeping in mind that thread pool should not be exhausted. I have kept below configuration.
apacheHttpClient:
maxConnections: 10
hystrix:
threadpool:
default:
coreSize: 100
executorService:
threadPool: 50

Have you considered feign w/Vertex? "Brings you the best of two worlds together : concise syntax of Feign to write client side API on fast, asynchronous and non-blocking HTTP client of Vertx." https://github.com/OpenFeign/feign-vertx
