This topic describes the native Redis commands supported by Tair (Enterprise Edition) and the limits on these commands. - Tair (Redis® OSS-Compatible)

Tair (Enterprise Edition) supports native Redis commands across multiple engine versions and instance types. Support varies by instance type and Redis version. This topic describes supported commands and any restrictions by instance type and version.

Supported Redis versions by instance type

Instance type	Compatible Redis versions	Notes
DRAM-based (Redis 7.0)	Redis 7.0 and earlier	Also supports Tair extended data structures
DRAM-based (Redis 6.0)	Redis 6.2 and earlier	Also supports Tair extended data structures
DRAM-based (Redis 5.0)	Redis 5.0 and earlier	Also supports Tair extended data structures
Persistent memory-optimized	Redis 6.0 and earlier	Additional command restrictions apply
ESSD/SSD-based	Redis 6.0 and earlier	Additional command restrictions apply

For restrictions specific to persistent memory-optimized and ESSD/SSD-based instances, see Additional limits for persistent memory-optimized and ESSD/SSD-based instances.

Command support tables

The following tables show command availability by Redis version for the latest minor version of each instance type.

Legend:

✔️ Supported
❌ Not supported
➖ Not applicable (command does not exist in this version)

Standard instances, cluster instances, and read/write splitting instances all support the command groups listed below by default. Cluster and read/write splitting instances have additional restrictions — see Limits on commands supported by cluster instances and read/write splitting instances.

Some commands are only available in later minor versions. Check Release notes for Tair minor versions and Release notes for minor versions of proxy nodes for version-specific details.

Cluster management

Cluster management commands are not supported on standard instances. If you connect via a proxy node endpoint, the following commands are available: CLUSTER INFO, CLUSTER KEYSLOT, CLUSTER NODES, CLUSTER SLAVES, and CLUSTER SLOTS.

To run commands marked with ① on a cluster instance, either enable direct connection mode using a private endpoint, or connect via a proxy node endpoint.

Server management

As a managed service, Tair handles persistence, replication, and server lifecycle automatically. Commands that would interfere with these managed operations are not available. To modify instance parameters or trigger administrative operations, use the Tair console or call the corresponding API operations.
