cluster keyslot, cluster countkeysinslot, cluster getkeysinslot, cluster slots, cluster shards. Among these, cluster shards is supported only by the standard and cluster architectures of Redis version 7.0 and Valkey versions 8.0 and 9.0. The other four commands are supported by the cluster architecture in Redis version 4.0 and all subsequent versions, but are not supported by the standard architecture. cluster slots returns the slot-to-node mapping, and cluster shards returns the slot-to-shard mapping (an improved version for 7.0+).cluster nodes, cluster info. These commands are supported by the cluster architecture in Redis version 4.0 and all subsequent versions, but are not supported by the standard architecture.cluster commands are not applicable (✗). In the cluster architecture, only slot query (cluster keyslot, cluster countkeysinslot, cluster getkeysinslot, cluster slots, cluster shards) and cluster information query (cluster nodes, cluster info) subcommands are supported. All other Ops management commands involving topology changes are globally unavailable. cluster shards is an improved version of cluster slots (introduced in Redis 7.0+), providing slot mapping information aggregated by shard.Command | Valkey 9.0 Standard Architecture | Valkey 9.0 Cluster Architecture | Redis 7.0 / Valkey 8.0 Standard Architecture | Redis 7.0 / Valkey 8.0 Cluster Architecture | Redis 6.2 Standard Architecture | Redis 6.2 Cluster Architecture | Redis 5.0 Standard Architecture | Redis 5.0 Cluster Architecture | Redis 4.0 Standard Architecture | Redis 4.0 Cluster Architecture | Redis 2.8 Standard Architecture | Cluster Architecture Support for Cross-Slot |
