Redis 4.0命令

华为云DCS Redis 4.0基于开源4.0.14版本进行开发,兼容开源的协议和命令。本章节主要介绍DCS Redis 4.0命令的兼容性,包括支持命令列表,禁用命令列表。

DCS Redis缓存实例支持Redis的绝大部分命令,任何兼容Redis协议的客户端都可以访问DCS。

Redis 4.0支持的命令

  • 表1表2列举了华为云Redis 4.0实例支持的Redis命令。
  • 表3表4列举了华为云Redis 4.0 Proxy集群支持的Redis命令。
  • 表5表6列举了华为云Redis 4.0读写分离支持的Redis命令。

各个命令的具体详细语法请前往Redis官方网站(中文网站为:http://www.redis.cn/commands.html)查看,例如您想了解SCAN命令的使用,可在Redis官方网站中搜索框中输入“SCAN”查询详细介绍。

  • Redis高版本的命令,在低版本中不被兼容。判断DCS Redis是否支持某个命令,可通过在Redis-cli执行该命令,如果得到(error)ERR unknown command ‘xxx’的提示,则说明不支持该命令。
  • Redis 4.0 Cluster版本集群实例使用pipeline时,要确保管道中的命令都能在同一分片执行。
