Distributed System Practice1. Consistent hashing algorithmHttp://www.javaranger.com/archives/1781?hmsr=toutiao.ioutm_medium=toutiao.ioutm_source=toutiao.ioKey points: The consistency hash algorithm is an effective method to solve the data partition of distributed system, and solves the problem that the traditional hash algorithm needs a large amount of mobile data when the machine is enlarged. This article gives a brief introduction to the consistent hash algorithm, so if you don't know the cons
I recently read some knowledge about design patterns and plan to record the learning process to further deepen my understanding.
In terms of the design pattern type, the simple factory pattern belongs to the creation pattern, also known as the staticfactory method pattern, but not one of 23 gof design patterns. In simple factory mode, a factory object determines the product type instance to create. The simple factory model is the simplest and Practical Model in the factory model family. It can
