Overview
When making an API call, you may pass ConfigureShard data as a hash:
{
node_group_id: "AllowedNodeGroupId", # required
new_replica_count: 1, # required
preferred_availability_zones: ["String"],
}
Node group (shard) configuration options when adding or removing replicas. Each node group (shard) configuration has the following members: NodeGroupId, NewReplicaCount, and PreferredAvailabilityZones.
Instance Attribute Summary collapse
-
#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` strings that specify which availability zones the replication group’s nodes are to be in.
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 replication group you are working with.
The minimum number of replicas in a shard or replication group is:
-
Redis (cluster mode disabled)
-
If Multi-AZ with Automatic Failover is enabled: 1
-
If Multi-AZ with Automatic Failover is not enable: 0
-
-
Redis (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 (cluster mode disabled) replication groups, the node group id is always 0001. To find a Redis (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 for Redis selects the availability zone for each of the replicas.
