Apache Pulsar vs Apache Kafka

Apache Kafka is a distributed streaming platform optimized for high-throughput log aggregation with 1M+ messages/sec per broker, while Apache Pulsar is a cloud-native pub/sub system with built-in multi-tenancy, geo-replication, and tiered storage that excels in complex messaging scenarios. Kafka dominates for simple event streaming; Pulsar wins for enterprise-grade messaging with advanced features.
