Part 6: Apache Kafka vs. NATS JetStream: Event Streaming Showdown
← Previous Chapter: Part 5 — Sharded MySQL vs. TiDB | Series Hub | Next Chapter: Part 7 — Modular Monolith vs. Microservices vs. SpinKube Wasm → Part 6: Apache Kafka vs. NATS JetStream: Event Streaming Showdown Answer-first: Apache Kafka (KRaft) excels in enterprise-scale event streaming, petabyte log retention, and strict partition-ordered analytics via OS page cache zero-copy I/O. Conversely, NATS JetStream is the optimal architecture for microservice meshes, edge deployments, and AI agent buses, offering sub-millisecond P99 latency, pure Go embedded Raft consensus, and 75% lower FinOps compute overhead. ...
