HomeDatabaseMysql TutorialMysql数据库常用分库和分表方式_MySQL

1 分库

1.1 按照功能分库

按照功能进行分库。常见的分成6大库:
1 用户类库:用于保存了用户的相关信息。例如:db_user,db_system,db_company等。
2 业务类库:用于保存主要业务的信息。比如主要业务是笑话,用这个库保存笑话业务。例如:db_joke,db_temp_joke等。
3 内存类库:主要用Mysql的内存引擎。前台的数据从内存库中查找,速度快。例如:heap。
4 图片类库:主要保存图片的索引以及关联。例如:db_img_index,db_img_res。
5 日志类库:记录点击,刷新,登录等日志信息。例如:db_log_click,db_log_fresh,db_log_login。
6 统计类库:对业务的统计,比如点击量,刷新量等等。例如db_stat。

1.2 安装城市站分库

如果业务遍布全国,在按照功能分库库,每一个城市复制一份一模一样的库,只是库后缀都是城市名称。比如db_log_click_bj,db_log_click_tj,db_log_click_sh;

2 分表

2.1 按照用户或业务的编号分表

对与用户或业务可以按照编号%n,进行分成n表。

例如:笑话表。

tb_joke_01,tb_joke_02,tb_joke_03,tb_joke_04........


2.2 按照日期分表

对于日志或统计类等的表。可以按照年,月,日,周分表。

例如 点击量统计。

tb_click_stat_201601,tb_click_stat_201602,tb_click_stat_201603
