on YouTube ↗48m

" summary

Compares concrete differences and demos: Pulsar separates storage to BookKeeper, auto‑rebalances topics, supports geo‑replication and tiered offload to S3, claiming millions of messages per second; shows creating an Astra tenant, deploying a Pulsar functions Java/Python lambda and observing logs. Shows a Spring app using a template.send with Kafka Streams, explains KRaft replacing ZooKeeper, and demonstrates using the Starlight Kafka API as a drop‑in bridge so existing Kafka apps talk to Pulsar — live deploys and examples that actually run.
