Redis 4.0支持及禁用的命令

华为云DCS Redis 4.0基于开源4.x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。

各个命令的具体详细语法请前往Redis官方网站查看，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。
