Comments description

The following sections show the description of the comments that are used in the tables of this topic:

  • ✔️ indicates that this command is supported.
  • ❌ indicates that this command is not supported.
  • ➖ indicates that the command is not supported in native Redis. For example, the TOUCH command is supported by only Redis 3.2.1 and later. This command is marked as ➖ in the Redis 2.8 column of the table.
  • Footnote 1: When you run the command on a cluster instance, you must enable direct connection to use a private endpoint to connect to the instance. For more information, see Use a private endpoint to connect to an ApsaraDB for Redis instance. You can run the command when you use the endpoint of a proxy node to connect to an instance.
  • Footnote 2: To be compatible with some client frameworks, when you run the CONFIG SET command, only OK is returned, and the parameters are not modified.
Note By default, commands in all command groups are supported by standard instances, cluster instances, and read/write splitting instances. For more information about instance types, see Overview.
