区分Python的redis客户端:hiredis、hiredis-py、redis-py

因为学习《Redis实战》用的是Python,须要按Python的redis客户端库。被几个库搞得有点晕,在此区分一下。git

区分hiredis、hiredis-py、redis-py

redis官网Github:https://github.com/redis,这里会看到两个项目:github

  1. hiredis --> 是一个C语言的redis客户端库
  2. hiredis-py --> 是Python语言包装了hiredis的redis客户端库

Andy McCurd的Github:https://github.com/andymccurdy,这里会看到一个项目:redis

  1. redis-py --> 是一个Python语言的redis客户端库

所以,hiredis-pyredis-py都是Python语言的库,二者没有直接关系。
安装方法:服务器

安装hiredis-py: pip install hiredis
安装redis-py: pip install rediside

Python文件中引入方法:性能

redis-py和hiredis-py的联系

redis-py文档 中能够看到这么一段内容:学习

Parser classes provide a way to control how responses from the Redis server are parsed. redis-py ships with two parser classes, the PythonParser and the HiredisParser. By default, redis-py will attempt to use the HiredisParser if you have the hiredis module installed and will fallback to the PythonParser otherwise.ui

译:Parser类能够控制如何解析Redis服务器端响应的内容。redis-py提供两个parser类,PythonParser和HiredisParser。若是你已经安装了hiredis模块,redis-py默认会尝试使用HiredisParser,不然会使用PythonParser。code

Hiredis is a C library maintained by the core Redis team. Pieter Noordhuis was kind enough to create Python bindings. Using Hiredis can provide up to a 10x speed improvement in parsing responses from the Redis server. The performance increase is most noticeable when retrieving many pieces of data, such as from LRANGE or SMEMBERS operations.orm

译:Hiredis是一个C语言的库,是由Redis核心团队维护的。Pieter Noordhuis还写了一个Python版本的Hiredis(即hireids-py)。使用Hiredis能够使得redis客户端解析服务端响应内容的速度提高10倍。并且当执行检索多条数据时性能更显著,如LRANGESMEMBERS等。

Hiredis is available on PyPI, and can be installed via pip or easy_install just like redis-py.

译:Hiredis能够在PyPI上找到,你能够使用easy_install或pip来安装(hiredis-py)。

$ pip install hiredis
or
$ easy_install hiredis

所以,安装redis-py同时安装hiredis-py,使用redis-py的时候会提高性能
