Batteries included: RabbitMQ clustering The clustering built in to RabbitMQ was designed with two goals in mind: allowing consumers and producers to keep running in the event one Rabbit node dies, and linearly scaling messaging throughput by adding m…

二.nova-api 步骤3:nova-api接收请求 nova-api接收请求,也不是随便怎么来都接收的,而是需要设定rate limits,默认的实现是在ratelimit的middleware里面实现的. 然而有时候,我们希望实现distributed rate-limiting,从而Turnstile是一个不错的选择. https://github.com/klmitch/turnstilehttp://pypi.python.org/pypi/turnstile 步骤4:对Token的…

RabbitMQ无疑是目前最流行的消息队列之一,对各种语言环境的支持也很丰富,作为一个.NET developer有必要学习和了解这一工具.消息队列的使用场景大概有3种: 1.系统集成,分布式系统的设计.各种子系统通过消息来对接,这种解决方案也逐步发展成一种架构风格,即“通过消息传递的架构”. 2.当系统中的同步处理方式严重影响了吞吐量,比如日志记录.假如需要记录系统中所有的用户行为日志,如果通过同步的方式记录日志势必会影响系统的响应速度,当我们将日志消息发送到消息队列,记录日志的子系统就会通过…

和RabbitMQ这个项目的缘分好奇怪,很长一段时间内是只关注源代码,真的是Erlang开源项目中的典范;现在要在项目中应用RabbitMQ,从新的视角切入,全新的感觉.仿佛旧情人换了新衣,虽是熟稔却有不曾领略的风情. RabbitMQ提供了一整套机制来处理消息的发送,接收,容错,管理,上一篇文章中我提到了一篇Rabbits and warrens的文章,是一篇非常棒的入门文章,但是里面忽略了不少细节,我沿着RabbitMQ in Action重新梳理了一遍,笔记于此,备忘. Exchanges…

一年前写了一篇短文ASP.NET MVC Action Filters,整理了Action Filter方面的资源,本篇文章详细的描述Action Filter.Action Filter作为一个可以应用到Controller Action(或者是整个controller)上的属性(Attribute),改变Action执行的行为,当应用于整个Controller上时,Controller上的所有Action都应用了同样设置的Action. 使用Action Filter 可以处理缓存. 验证和…
