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 |
