Beyond Kafka: Leveraging Event-Driven Architectures with Go and NATS JetStream

on YouTube ↗25m

" summary

Claims that NATS JetStream replaces Kafka for small-to-medium workloads with far lower resource use: an example migration cuts broker CPU/memory from ~95% to ~10% and now to ~5% while handling ~50 million messages/day. Demonstrates Go code that publishes JSON "order" events, creates durable consumers, ack processing, and uses an embedded server for tests. Notes JetStream gives streams+consumers semantics, easier deployment and replication, but ordering and partition guarantees require extra manual setup.
