RabbitMQ vs. Apache Kafka: Key Differences and Use Cases

Asynchronous Messaging Patterns

Message Queues

Publish/Subscribe

RabbitMQ

Architecture

Queues

Message Exchanges

  • Direct exchanges route messages according to the routing key that the message carries. The routing key is a string of words, separated by periods, that has some relevance to the message.
  • Fanout exchanges route messages to all available queues. In this broadcasting type of exchange, the routing key is ignored.
  • Topic exchanges route messages to one or more queues according to a complete or partial match with the routing key.
  • Header exchanges route messages based on the message headers, which can contain more attributes than a routing key.

Apache Kafka

  • Scalability: Kafka’s distributed architecture enables significant horizontal scalability.
  • Performance: Kafka is fast! It can process millions of messages per second with relatively modest resources.
  • Flexibility: Designed to interface with a variety of systems, Kafka has useful, intuitive APIs.
  • Availability: Kafka delivers high availability through load balancing and data replication.
  • Community: As part of the Apache Software Foundation, Kafka has a rich ecosystem and community.
  • Strong reputation: Kafka is used by leading, high-profile organizations, including not only LinkedIn but also Netflix, Twitter, Spotify, Pinterest, Airbnb, Uber, and many others.
