ConfigureShard
Node group (shard) configuration options when adding or removing replicas. Each node group (shard) configuration has the following members: NodeGroupId, NewReplicaCount, and PreferredAvailabilityZones.
Types
Properties
The number of replicas you want in this node group at the end of this operation. The maximum value for NewReplicaCount
is 5. The minimum value depends upon the type of Valkey or Redis OSS replication group you are working with.
The 4-digit id for the node group you are configuring. For Valkey or Redis OSS (cluster mode disabled) replication groups, the node group id is always 0001. To find a Valkey or Redis OSS (cluster mode enabled)'s node group's (shard's) id, see Finding a Shard's Id.
A list of PreferredAvailabilityZone
strings that specify which availability zones the replication group's nodes are to be in. The nummber of PreferredAvailabilityZone
values must equal the value of NewReplicaCount
plus 1 to account for the primary node. If this member of ReplicaConfiguration
is omitted, ElastiCache selects the availability zone for each of the replicas.
The outpost ARNs in which the cache cluster is created.
