Pulsar vs Kafka

Both Pulsar and Kafka can guarantee the delivery of messages to intended recipients. Yet, they differ in complexity and modularity, latency and throughput. Another key distinction: Kafka ensures exactly once processing at the consumer level. Pulsar only confirms exactly once in the Pulsar store.

Whether using Kafka or Pulsar, we recommend you focus on reliability. You can do this by creating an implementation that is as simple as possible.
