Pulsar vs Kafka
Compare multiple streaming and messaging technologies
What is the difference between Pulsar and Kafka?
Kafka is a proven high-throughput event stream designed for durable, replayable logs, suitable for big data and real-time analytics. Pulsar is a cloud-native, unified messaging platform that combines streaming and traditional queuing, offering built-in multi-tenancy and better scalability for diverse workloads.
