High Availability of rabbitmq Clusters Rabbitmq is developed using Erlang and clusters are very convenient. Because Erlang is a distributed language, it does not support Server Load balancer itself. The rabbit mode can be divided into the following three modes: single mode, normal mode, and image mode. Single Mode: the simplest mode, not the cluster mode. There i
RABBITMQ Cluster High AvailabilityRABBITMQ is developed with Erlang, which is very handy because Erlang is inherently a distributed language, but it does not natively support load balancing.Rabbit mode is roughly divided into the following three types: Single mode, normal mode, mirror modeSingle mode: The simplest case, non-clustered mode.There's nothing to say.Normal mode: The default
"ABC" is set to be posted to the queue. When the key is matched with a pattern, it is called a topic switch, and the symbol "#" matches one or more words, and the symbol "*" matches exactly one word. For example, "abc.#" matches "Abc.def.ghi", "abc.*" matches only "Abc.def". There is also a need for a key, called the fanout Switch, which takes broadcast mode, when a message comes in, it is posted to all queues that are bound to the switch. RABBITMQ s

RABBITMQ Introduction 1, What is RABBITMQ? MQ is all called MessageQueue, and Message Queuing (MQ) is an application-to-application communication method. Applications communicate by writing and retrieving data (messages) for applications that enter and leave the queue, without requiring a private connection to link them.RabbitMQ is an open-source implementation of the AMQP (Advanced Message Queuing

What is RABBITMQ? MQ (Message queue) message middleware, which is generally deployed in cluster mode, mainly provides the receiving and sending of messages, and realizes the synchronization of messages between each micro-service.
