环境：Python 3.5+, Django 1.9+

最初用django时，搜索时发现PyMySQL的文章很多，然而在django的官方文档中python3版的mysql客户端驱动确没有提到PyMySQL，只提到了mysqlclient，再细看下去发现：

1. 两个库的作者是同一个人INADA Naoki, pip库邮箱都指向mailto:songofacandy@gmail.com

2. PyMySQL的代码人员methane说mysqlclient速度更快及PyMySQL的应用场景，参见：https://github.com/PyMySQL/PyMySQL/issues/342 

 mysqlclient-python is much faster than PyMySQL.
When to use PyMySQL is:

• You can‘t use libmysqlclient for some reason
• You want to use monkeypatched socket of gevent or eventlet
• You wan‘t to hack mysql protocol

3. Django1.9.12官方文档中：

Django requires mysqlclient 1.3.3 or later. Note that Python 3.2 is not supported. Except for the Python 3.3+ support,
mysqlclient should mostly behave the same as MySQLDB.

4. https://python.libhunt.com/project/mysqlclient-python/vs/pymysql  两者基本面的对比

经上对比，准备先用mysqlclient！
