Redis 4.0 Commands

DCS for Redis 4.0 is developed based on Redis 4.0.14 and is compatible with open-source protocols and commands.

This section describes DCS for Redis 4.0's compatibility with Redis commands, including supported and disabled commands. For more information about the command syntax, visit the Redis official website.

DCS for Redis instances support most Redis commands, which are listed in Commands Supported by DCS for Redis 4.0. Any client compatible with the Redis protocol can access DCS.

Commands Supported by DCS for Redis 4.0

Table 1 and Table 2 list the Redis commands supported by single-node, master/standby, and Redis Cluster DCS Redis 4.0 instances.

Note

  • Commands available since later Redis versions are not supported by earlier-version instances. Run a command on redis-cli to check whether it is supported by DCS for Redis. If the message "(error) ERR unknown command" is returned, the command is not supported.

  • For DCS Redis 4.0 instances in the Redis Cluster mode, ensure that all commands in a pipeline are executed on the same shard.
