    Articles by Eran Stiller:

    • RabbitMQ vs. Kafka – An Architect’s Dilemma (Part 1)
    • RabbitMQ vs. Kafka – An Architect’s Dilemma (Part 2)

    • SO: When to use RabbitMQ over Kafka?
    • When to use RabbitMQ or Apache Kafka

    Benchmarks by Confluent.io (Kafka creator and Cloud Provider), seem heavily biased towards Kafka:

    • Kafka vs. Pulsar vs. RabbitMQ: Performance, Architecture, and Features Compared
    • Benchmarking Apache Kafka, Apache Pulsar, and RabbitMQ: Which is the Fastest?
