Redis 5.0命令
DCS Redis 5.0基于开源5.0.14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 5.0命令的兼容性，包括支持命令列表，禁用命令列表。命令的具体详细语法，请前往Redis官方网站查看。
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
- 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。
