Redis 5.0 Commands

DCS for Redis 5.0 is developed based on Redis 5.0.9 and is compatible with open-source protocols and commands.

This section describes DCS for Redis 5.0'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. Any client compatible with the Redis protocol can access DCS.

For security purposes, some Redis commands are disabled in DCS, as listed in Commands Disabled by DCS for Redis 5.0.
Some Redis commands are supported by cluster DCS instances for multi-key operations in the same slot. For details, see Command Restrictions for Cluster Instances.
Some Redis commands have usage restrictions, which are described in Other Command Usage Restrictions.
