Commands Supported and Disabled by DCS for Redis 6.0

Huawei Cloud DCS for Redis 6.0 is fully compatible with open-source Redis 6.

This section describes DCS for Redis 6.0's compatibility with KeyDB commands, including supported and disabled commands.

For more information about the command syntax, visit the Redis official website.

DCS 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 6.0.
Some Redis commands are supported by cluster DCS instances for multi-key operations in the same slot. For details, see Command Restrictions.
Some Redis commands (such as KEYS, FLUSHDB, and FLUSHALL) have usage restrictions, which are described in Other Command Usage Restrictions.
Some high-risk commands can be renamed. For details, see Commands That Can Be Renamed.
