3 common pitfalls in microservice integration and how to avoid them
summary
Three concrete pitfalls and how they’re fixed: thread exhaustion from slow downstreams (demo showed a 59 second random delay that blocks threads) solved with a circuit breaker (Hystrix style / Resilience4j) and by returning 202 accepted while kicking off durable workflows. Long timeouts require stateful retry stored in a workflow engine (embedded in a Spring Boot app in the demo), plus saga-style compensation instead of XA so services stay consistent if retries or cleanups are needed. REST still dominates (70–80%); idempotency is mandatory.
