RabbitMQ整体架构 1. 主流消息中间件 ActiveMQ 最流行，完全支持JMS规范，不适合在高并发下使用，API丰富 性能不好 Kafka 分布式发布-订阅消息系统，基于pull模式来处理消息，追求吞吐量，不支持十五，对消息的重复，丢失，错误没有严格要求 关注性能 RocketMQ 阿里开源 Java编写 高吞吐高性能 适合大规模分布式系统，思路起源于Kafka 保证消息顺序 支持分布式事务 上亿消息堆积 商业版收费 RabbitMQ Erlang开发 AMQP协议实现 一致性，稳定性，可靠性比较好。 对性能和吞吐量的要求还在其次 2. 衡量一个MQ指标 服务性能 数据存储 集群架构 3.

I am trying to build the RabbitMQ PHP wrapper and the AMPQ PHP wrapper on Windows (64) using Cygwin. I have successfully built the underlying C library (librabbitmq.dll) but I am stuck at the 'phpize' step: phpize && ./configure --with-rabbit && make && sudo make install If I understand correctly, there is no 'phpize' on windows, so how do I build my PHP wrapper? Note that I'm totally new to building PHP extensions (be it on linux or windows). Theodore R. Smith This is totally not supported. PHP is designed to be compiled with GNUmake on UNIX/POSIX systems and Visual C++ on Windows systems.

We are writing C++ code which needs messaging. Is there a free/open-source and stable AMQP server available that has equally stable C++ client library with it. We also need to provide Python interface of our code to users (idea is to do maximum stuff in C++ and expose the API in Python). What can be best way to achieve this. For future reference, take a look at Apache Qpid - it has a C++ client library and is very good. The problem for your use-case is that Rabbit implements AMQP 0-8 and the Qpid C++ client talks AMQP 0-10. Apache QPid seems to be relevant here. There's a C++ broker/client

Similar questions all seem to be based around using a custom logger, I'm happy to just use the default / none at all. My pika python app runs and receives messages but after a few seconds crashes with No handlers could be found for logger "pika.adapters.blocking_connection" , any ideas? import pika credentials = pika.PlainCredentials('xxx_apphb.com', 'xxx') parameters = pika.ConnectionParameters('bunny.cloudamqp.com', 5672, 'xxx_apphb.com', credentials) connection = pika.BlockingConnection(parameters) channel = connection.channel() channel.queue_declare('messages') def message_received(channel

It looks like celery does not release memory after task finished. Every time a task finishes, there would be 5m-10m memory leak. So with thousands of tasks, soon it will use up all memory. BROKER_URL = 'amqp://user@localhost:5672/vhost' # CELERY_RESULT_BACKEND = 'amqp://user@localhost:5672/vhost' CELERY_IMPORTS = ( 'tasks.tasks', ) CELERY_IGNORE_RESULT = True CELERY_DISABLE_RATE_LIMITS = True # CELERY_ACKS_LATE = True CELERY_TASK_RESULT_EXPIRES = 3600 # maximum time for a task to execute CELERYD_TASK_TIME_LIMIT = 600 CELERY_DEFAULT_ROUTING_KEY = "default" CELERY_DEFAULT_QUEUE = 'default'

For message-oriented middleware that does not consistently support priority messages (such as AMQP) what is the best way to implement priority consumption when queues have only FIFO semantics? The general use case would be a system in which consumers receive messages of a higher priority before messages of a lower priority when a large backlog of messages exists in Queue(s). Given only FIFO support for a given single queue, you will of course have to introduce either multiple queues, an intermediary, or have a more complex consumer. Multiple queues could be handled in a couple of ways. The
