What‘s a MQ

What‘s a MQ queue

What‘s a MQmessage queue

What‘s a MQ messageProducer queue

What‘s a MQ Consumer messageProducer queue

Why MQDe-coupleHigher performanceAnother IPC

Why rabbitMQ?Based on Erlang Reliable Highly available Scalable portableImplemented AMQP Standard and More100% OpenSource

I have a log system

register Loginlogout Log System DataBase

register Login log = getLog(request) if log.type == ‘login’:logout # balabala ....... if log.type == ‘register’: # balabala ....... log.save() Log System DataBase

register Login log = getLog(request) if log.type == ‘login’: logout # balabala ....... if log.type == ‘register’: # balabala ....... log.save() Log SystemI need ...1. better performance2. cleaner code DataBase3. easier to test4. ....

Step1. work with Queue

Step1. work with Queue.......log = getLog(request)channel.publish(None,‘log-queue’,None,log)

Step1. work with Queue.......log = getLog(request)channel.publish(None,‘log-queue’,None,log) def onLog(log): if log.type == ‘login’: # balabala if log.type == ‘logout’: # balabala log.save()

Step1. work with Queue.......log = getLog(request)channel.publish(None,‘log-queue’,None,log) def onLog(log): if log.type == ‘login’:yep. performance better now # balabalabut. that if log.type == ‘logout’:codes still smell bad~~ # balabala log.save()

step2. Split Queues login logout

step2. Split Queues.......log = getLog(request)channel.publish(None,log.type,None,log) login logout

step2. Split Queues....... def onLog(loginlog):log = getLog(request) # balabalachannel.publish(None,log.type,None,log) loginlog.save() login logout

step2. Split Queues....... def onLog(loginlog):log = getLog(request) # balabalachannel.publish(None,log.type,None,log) loginlog.save() login logout def onLog(logoutlog): # balabala logoutlog.save()

step2. Split Queues....... def onLog(loginlog):log = getLog(request) # balabalachannel.publish(None,log.type,None,log) loginlog.save() login logout def onLog(logoutlog): # balabalaWhat’s that guy? logoutlog.save()

Say hi to Exchange

Direct Exchange

Fanout Exchange

Topic Exchange

step3. Share message c# x login c1P x c2 logout

step3. Share message.......log = getLog(request)channel.exchange_declare(log.type,‘fanout’)channel.publish(log.type,’’,None,log) c# x login c1 P x c2 logout

step3. Share message.......log = getLog(request) def onLog(loginlog):channel.exchange_declare(log.type,‘fanout’) # balabalachannel.publish(log.type,’’,None,log) loginlog.save() c# x login c1 P x c2 logout

step3. Share message.......log = getLog(request) def onLog(loginlog):channel.exchange_declare(log.type,‘fanout’) # balabalachannel.publish(log.type,’’,None,log) loginlog.save() c# x login c1 P x c2 logout def onLog(logoutlog): # balabala logoutlog.save()
