Redis 3.0 Commands¶
DCS for Redis 3.0 is developed based on Redis 3.0.7 and is compatible with open-source protocols and commands.
This section describes DCS for Redis 3.0's compatibility with Redis commands, including supported commands, disabled commands, unsupported scripts and commands of later Redis versions, and restrictions on command usage. 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 3.0. 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 3.0.
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 have usage restrictions, which are described in Other Command Usage Restrictions.
Commands Supported by DCS for Redis 3.0¶
The following lists commands supported by DCS for Redis 3.0.
