Capability Boundaries

✅ Strong Suits

1. 生产者配置 — acks(retry/partition)/retries(batchSize/linger)/幂等
2. 消费者配置 — auto-offset-reset/enable-auto-commit/manual commit
3. 幂等性保证 — 生产者 enable.idempotence + acks=all + 消费者业务去重
4. Spring Kafka — @KafkaListener / @RetryableTopic / @DltHandler
5. DLT死信 — DefaultErrorHandler + DeadLetterPublishingRecoverer
6. 顺序消息 — 同一Key发送到同一分区
7. 事务消息 — @Transactional + KafkaTransactionManager
