Kafka 3.9 made KRaft the default and ZooKeeper is gone. WarpStream put the Kafka API on top of S3 and was acquired by Confluent. Redpanda pushes Kafka compatibility in C++, NATS became a single-infra play with JetStream/KV/ObjectStore, and Pulsar 4.0 runs code on streams with Functions. RabbitMQ 4.0 dropped Mnesia for Khepri (Raft). We cover Kafka, NATS, Redpanda, Pulsar, RabbitMQ 4, RocketMQ, NSQ, Memphis (Superstream), WarpStream, and Buf Stream — paradigms, operations, cost, and KR/JP adoption — in one go.

Kafka 3.9는 KRaft가 기본이 되었고 ZooKeeper는 사라졌다. WarpStream은 S3 위에 Kafka API를 올렸고 Confluent에 인수됐다. Redpanda는 C++로 Kafka 호환을 밀고, NATS는 JetStream/KV/ObjectStore로 단일 인프라가 되었으며, Pulsar 4.0은 Functions로 스트림 위에서 코드를 돌린다. RabbitMQ 4.0은 Mnesia를 버리고 Khepri(Raft)를 채택했다. Kafka·NATS·Redpanda·Pulsar·RabbitMQ 4·RocketMQ·NSQ·Memphis(Superstream)·WarpStream·Buf Stream을 패러다임·운영·비용·KR/JP 사례까지 한 번에 정리한다.
