php - 格式化队列消息的最佳方式是什么？

Question

我最近一直在研究消息队列，我想为我的应用程序实现一个简单、可扩展的系统。虽然有很多关于设置 MQ 系统的有用信息，但我找不到很多关于实际实现的信息。

我正在寻找关于如何正确格式化队列消息的模式和最佳实践，以及在 PHP 中执行作业的方法。我应该使用 JSON、序列化对象、文本、URL 还是 XML？我应该发送什么信息？使用 switch($job['command']) {}(或类似的东西)的工作器是否可行，或者是否有任何既定的模式来实现工作器？

非常感谢帮助!

您可以在 PHP 中选择以下任何 MQ 实现，这样您就不必自己动手，您可以查看它们的源代码以了解它们的实现。对于一般集成，请查看 ActiveMQ page on Enterprise Integration patterns .

• http://sourceforge.net/projects/beanstalk/

  A PHP Client Library for beanstalkd. BeanStalk allows PHP developers to make use of the beanstalkd in-memory workqueue server (http://xph.us/software/beanstalkd).

• http://kr.github.com/beanstalkd/

  Beanstalk is a simple, fast workqueue service. Its interface is generic, but was originally designed for reducing the latency of page views in high-volume web applications by running time-consuming tasks asynchronously.

• http://activemq.apache.org/

  Apache ActiveMQ is the most popular and powerful open source messaging and Integration Patterns provider. Apache ActiveMQ is fast, supports many Cross Language Clients and Protocols, comes with easy to use Enterprise Integration Patterns and many advanced features while fully supporting JMS 1.1 and J2EE 1.4. Apache ActiveMQ is released under the Apache 2.0 License

• http://memcachedb.org/memcacheq/

  Memcachedb is a distributed key-value storage system designed for persistent. It is not a cache solution, but a persistent storage for high-frequency writing and reading. It conforms to memcache protocol(not completed, see below), so any memcached client can have connectivity with it. Memcachedb uses Berkeley DB as a storing backend, so lots of features including transaction and replication are supported.

• http://www.zend.com/en/products/server/

  Zend Server 5.0 incorporates Job Queue, providing full support for creating, executing and managing jobs to optimize application performance and reduce server load, minimizing application bottlenecks and improving the end-user experience.

• https://www.dropr.org/

  dropr is a distributed message queue framework written in PHP. The main goals are:

  • reliable and durable (failsafe)-messaging over networks
  • decentralized architecture without a single (point of failure) server instance
  • easy to setup and use
  • modularity for queue storage and message transports (currently filesystem storage and curl-upload are implemented)

• http://gearman.org/

  Gearman provides a generic application framework to farm out work to other machines or processes that are better suited to do the work. It allows you to do work in parallel, to load balance processing, and to call functions between languages.

• http://www.zeromq.org/

  ØMQ (also spelled ZeroMQ, 0MQ or ZMQ) is a high-performance asynchronous messaging library aimed at use in scalable distributed or concurrent applications. It provides a message queue, but unlike message-oriented middleware, a ØMQ system can run without a dedicated message broker. The library is designed to have a familiar socket-style API.
