MQ Achieves Traffic Buffering With Client Pull Mode
MQ buffers traffic, preventing peaks & valleys. Downstream systems protected with client pull mode, reducing excessive traffic overload.
Message Queuing (MQ) has many application scenarios, such as message publishing and subscription, decoupling between upstream and downstream systems. One typical use of MQ is to buffer traffic, helping to shave peaks and fill valleys. How do upstream and downstream systems usually communicate? There are two common communication methods: Direct Call: Through an RPC framework, the upstream system directly calls the downstream system. MQ Push: The upstream system sends messages to the MQ, and the MQ pushes the messages to the downstream system. Can these methods cache traffic or a...
