About This Launch
A Spring Boot 4.1 event-driven starter for Java developers building reliable Kafka-based systems. Includes the transactional outbox pattern, idempotent consumers, retries with dead-letter topics (DLT), and 16 tests (9 using EmbeddedKafka). $25 one-time purchase, full source code under a personal developer license.
Why I Built This
Getting Kafka reliability right (no lost or duplicated events) takes a lot of trial and error. I packaged the proven outbox + idempotency + DLT setup I use so others can start from a solid, tested base.
