developed using the Erlang language, which is implemented based on the AMQP protocol. The main features of AMQP are message-oriented, queue, routing (including point-to-point and publish/subscribe), reliability, and security. The AMQP protocol is more used in enterprise systems, where the requirements for data consistency, stability, and reliability are high, and the performance and throughput requirements are second. ROCKETMQ is Ali open source of the message middleware, it is pure
