华为云DCS Redis 5.0基于开源5.0.9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 5.0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。
● 因安全原因，部分Redis命令在分布式缓存服务中被禁用，具体请见Redis 5.0禁用 的命令。
● DCS集群实例支持多个key，但不支持跨slot访问的Redis命令列表，如实例受限使 用命令所示。
● 部分Redis命令使用时有限制，具体请见部分命令使用限制。
Redis 5.0 支持的命令
● 表5-15和表5-16列举了Redis 5.0实例支持的命令。
● 表5-17和表5-18列举了Redis 5.0 proxy集群支持的命令。
● 表5-19和表5-20列举了Redis 5.0读写分离支持的命令。
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。
说明
● 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 5.0 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。
