, can handle this kind of problem correctly, let the distributed system run normally. Zookeeper Typical application scenariosZookeeper, from the design pattern perspective, is a distributed service management framework based on the observer pattern, which is responsible for storing and managing the data that everyone cares about, then accepting the observer's registration, and once the status of the data changes, zookeeper will be responsible for not

A large WEB development plan typically consists of multiple development projects that are synchronized 24x7 by a team of geographically dispersed teams. The various components developed by these teams need to achieve seamless interoperability as much as possible. The key requirement for this type of development is to establish a good agreement between the teams responsible for building the different components. A good simulator framework ensures as mu

If there is no guiding ideology in the code design process, it is easy to confuse the code file, such: it is as difficult as naming multiple controls or variables if a class or method doesn't know where to put them; In the process of using the framework in the project, we can l

In August 2011, I wrote a blog, "using the CodeIgniter framework to build RESTful API services," describing restful design concepts and how to implement restful APIs using the CodeIgniter framework. Two years later, rest has improved a lot in the past two years. I am not very satisfied with some aspects of the previous blog, so I hope to use this opportunity to w
