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.
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 4.0.
- 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 4.0
- Table 1 and Table 2 list the Redis commands supported by DCS Redis 4.0 instances.
- Table 3 and Table 4 list the Redis commands supported by Proxy Cluster DCS Redis 4.0 instances.
- Table 5 and Table 6 list the Redis commands supported by read/write splitting DCS Redis 4.0 instances.
For details about the command syntax, visit the Redis official website. For example, to view details about the SCAN command, enter SCAN in the search box on this page.
- 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.
