详解Redis中key的命名规范和值的命名规范

时间：2021-08-26 08:18:35

数据库中得热点数据key命名惯例

  表名:主键名:主键值:字段名
例如 user:id:0001:name
例如 user:id:0002:name
例如 order:id:s2002:price

上面的key对应的值则可以是

存放的方式 key value 优点
单独的key:value形式 order:id:s2002:price 2000 方便简单的操作，例如incr自增或自减
json格式 user:id:0001 {id:0001,name:"张三"} 方便一次性存和取数据，但是不方便更新数据
