Overview
Node group (shard) configuration options when adding or removing replicas. Each node group (shard) configuration has the following members: NodeGroupId, NewReplicaCount, and PreferredAvailabilityZones.

#new_replica_count ⇒ Integer
The number of replicas you want in this node group at the end of this operation.
-
#node_group_id ⇒ String
The 4-digit id for the node group you are configuring.
-
#preferred_availability_zones ⇒ Array<String>
A list of
PreferredAvailabilityZone

#preferred_outpost_arns ⇒ Array<String>
The outpost ARNs in which the cache cluster is created.
Instance Attribute Details
#new_replica_count ⇒ Integer
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 Redis OSS replication group
you are working with.
The minimum number of replicas in a shard or replication group is:
Redis OSS (cluster mode disabled)
If Multi-AZ: 1
If Multi-AZ: 0
Redis OSS (cluster mode enabled): 0 (though you will not be able to failover to a replica if your primary node fails)

#node_group_id ⇒ String
The 4-digit id for the node group you are configuring. For Redis OSS (cluster mode disabled) replication groups, the node group id is always 0001. To find a Redis OSS (cluster mode enabled)'s node group's (shard's) id, see Finding a Shard's Id.

#preferred_availability_zones ⇒ Array<String>
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 (Redis OSS)
selects the availability zone for each of the replicas.
