ApsaraDB for Redis Community Edition provides instances of multiple editions and architectures. The commands supported by the instances vary with their instance types. This topic describes the native Redis commands supported by ApsaraDB for Redis Community Edition and the limits of these commands.

Precautions

To simplify management and O&M, cluster and read/write splitting instances support multiple commands that are developed by Alibaba Cloud. For more information, see Redis commands developed by Alibaba Cloud.

Symbols in the tables

This section describes the symbols 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 open source Redis. For example, the TOUCH command is supported only by Redis 3.2.1 and later. This command is marked as ➖ in the Redis 2.8 column of the table.
  • Footnote ①: If you want to run the command on a cluster instance, you must enable the direct connection mode 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 also run the command if you use the endpoint of a proxy node to connect to an instance.
  • Footnote ②: The CONFIG SET command returns only OK. The command does not modify the parameters. This ensures that the instance remains compatible with specific client frameworks.
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 architectures, see Overview.

Supported command groups

Cluster command group

Note
  • The commands in the cluster command group are not supported by standard instances.
  • However, if you use the endpoint of a proxy node to connect to an instance, specific commands in the cluster command group are supported. These commands include CLUSTER INFO, CLUSTER KEYSLOT, CLUSTER NODES, CLUSTER SLAVES, and CLUSTER SLOTS.
  • The READONLY and READWRITE commands are supported as of minor versions 0.1.14 of ApsaraDB for Redis 5.0 and 6.0.
