  21. Big Data Integration - RabbitMQ vs Kafka
    Kafka
    RabbitMq
    • RabbitMQ is designed as a general
    purpose message broker
    • Support existing protocols like
    AMQP, STOMP, MQTT.
    • Finer-grained consistency
    control/guarantees on a peer-
    message.
    • Complex routing.
    • Apache Kafka is designed for high
    volume publish-subscribe
    messages and streams, meant to
    be durable, fast, and scalable.
    • Event Sourcing
    • Your application needs access to
    stream history.
    • No complex routing.
