amqp

I have installed celery and RabitMQ and flower. I am able to browse to the flower port. I have the following simple worker that I can attach to celery and call from a python program: # -*- coding: utf-8 -*- """ Created on Sat Dec 12 16:37:33 2015 @author: idf """ from celery import Celery app = Celery('tasks', broker='amqp://guest@localhost//') @app.task def add(x, y): return x + y This program calls it # -*- coding: utf-8 -*- """ Created on Sat Dec 12 16:40:16 2015 @author: idf """ from tasks import add add.delay(36, 5) I start celery like this: idf@DellInsp:~/Documents/Projects/python3$

AMQP C++ implementation (5 answers) Is there a AMQP implementation that has stable C++ Client library Dave Apache Qpid has a stable C++ client library -- see qpid.apache.org .

I wanted a feedback on whether my evaluations and concerns are correct. I have been reseaching the three, Data Distribution Service, AMQP and ZeroMQ for sometime now for building a data transport layer in a datacenter. All the three look promising, yet i encountered some blocking issues in few. To give a context, my requirements are: Scale upto 500+ physical nodes, 1000+ publishers and subscribers. Support durable delivery of messages to take care of failing subscribers. The aggregated throughput should be north of 1 Million messages / sec Problems with AMQP: The Broker architecture seems to

Below is the desirable design of the queue with: P producer. The application that insert data X exchange. C1-C3 consumer. The applications that read from the queue Queue details: A. Is just like queue log, if there is no client binding then message will be discarded. B. This is a working queue. it will do something if there is criteria match. C. Also a working queue. it will transform the data A is optional, but B. C. will always in queue until some client process connect it. The problem is determine which type of exchange that i should use. is it a fanout, direct or topic ? because I wanted

I have a simple RabbitMQ test program randomly enqueuing messages, and another reading them, all using Spring-AMQP. If the consumer dies (for example killing a process without having a chance to close its connection or channel), any messages that it had not acknowledged appear to remain unacknowledged forever. I have seen a number of references (for example this question ) that say that the channel dies when it has no connections, and that remaining unack'd messages will be redelivered. That's not the behaviour I see - instead I get a growing list of channels marked IDLE and a growing list of

Is it possible with RabbitMQ and Python to do content-based routing? The AMQP standard and RabbitMQ claims to support content-based routing, but are there any libraries for Python which support specifying content-based bindings etc.? The library I am currently using (py-amqplib http://barryp.org/software/py-amqplib/ ) seems to only support topic-based routing with simple pattern-matching (#, *). The answer is "yes", but there's more to it... :) Let's first agree on what content-based routing means. There are two possible meanings. Some people say that it is based on the header portion of a
