Build a production-oriented gRPC service with Spring Boot 4.1, evolve Protocol Buffer contracts safely, enforce deadlines, map failures to status codes, test with an in-process transport, and decide where Java virtual threads actually help.- Published on
Design a recoverable Spring Kafka consumer by classifying failures, bounding retries, preserving record context, making database effects idempotent, testing rebalances and poison records, and rehearsing DLT replay.
