Selection guide for message queue middleware in java framework

The selection of message queue middleware in the Java framework depends on the evaluation criteria (performance, reliability, scalability, fault tolerance, ease of use and support) and practical cases: Performance: Apache Kafka, Pulsar high performance, RabbitMQ, ActiveMQ has lower performance. Reliability: Kafka provides a one-time guarantee, Pulsar and RabbitMQ provide a guarantee, and ActiveMQ provides a low guarantee. Scalability: Kafka and Pulsar have high scalability, RabbitMQ and ActiveMQ have medium scalability. Fault tolerance: Kafka and Pulsar have high fault tolerance, RabbitMQ has medium fault tolerance, and ActiveMQ has low fault tolerance. Ease of use:
