1、Work queues
work queues compared with the entry procedures, more than a consumer side, two common consumer end consumer with a message in the queue.
Scenario: too heavy for the task or tasks in many cases, the use of the work queue can improve the speed of processing tasks.
Test:
1, Getting Started, launch multiple consumers.
2, a plurality of producers transmit messages.
Results:
1, a received message will only be a consumer;
2, Rabbit way polling message is sent to the average consumer;
3, a consumer after handling messages, will receive the next messages.
A producer more consumers. Simultaneously process multiple message consumers embodiment, the cyclic polling message sent to the respective consumer
test
More consumers start
to start the three, the equivalent of three consumers to listen to the same queue.
We can see a total of three links
Run producer
of a consumer receives a message
a second client reception
Repeatedly turns each consumer receives a message sent
