    • numCacheClusters

      public final Integer numCacheClusters()

      The number of clusters this replication group initially has.

      This parameter is not used if there is more than one node group (shard). You should use ReplicasPerNodeGroup instead.

      If AutomaticFailoverEnabled is true, the value of this parameter must be at least 2. If AutomaticFailoverEnabled is false you can omit this parameter (it will default to 1), or you can explicitly set it to a value between 2 and 6.

      The maximum permitted value for NumCacheClusters is 6 (1 primary plus 5 replicas).

      Returns:
      The number of clusters this replication group initially has.

      This parameter is not used if there is more than one node group (shard). You should use ReplicasPerNodeGroup instead.

      The maximum permitted value for NumCacheClusters is 6 (1 primary plus 5 replicas).

    • hasPreferredCacheClusterAZs

      public final boolean hasPreferredCacheClusterAZs()
      For responses, this returns true if the service returned a value for the PreferredCacheClusterAZs property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • preferredCacheClusterAZs

      public final List<String> preferredCacheClusterAZs()

      A list of EC2 Availability Zones in which the replication group's clusters are created. The order of the Availability Zones in the list is the order in which clusters are allocated. The primary cluster is created in the first AZ in the list.

      This parameter is not used if there is more than one node group (shard). You should use NodeGroupConfiguration instead.

      If you are creating your replication group in an Amazon VPC (recommended), you can only locate clusters in Availability Zones associated with the subnets in the selected subnet group.

      The number of Availability Zones listed must equal the value of NumCacheClusters.

      Default: system chosen Availability Zones.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasPreferredCacheClusterAZs() method.

      Returns:
      A list of EC2 Availability Zones in which the replication group's clusters are created. The order of the Availability Zones in the list is the order in which clusters are allocated. The primary cluster is created in the first AZ in the list.

      This parameter is not used if there is more than one node group (shard). You should use NodeGroupConfiguration instead.

      If you are creating your replication group in an Amazon VPC (recommended), you can only locate clusters in Availability Zones associated with the subnets in the selected subnet group.

      The number of Availability Zones listed must equal the value of NumCacheClusters.

      Default: system chosen Availability Zones.

    • numNodeGroups

      public final Integer numNodeGroups()

      An optional parameter that specifies the number of node groups (shards) for this Redis (cluster mode enabled) replication group. For Redis (cluster mode disabled) either omit this parameter or set it to 1.

      Default: 1

      Returns:
      An optional parameter that specifies the number of node groups (shards) for this Redis (cluster mode enabled) replication group. For Redis (cluster mode disabled) either omit this parameter or set it to 1.

      Default: 1

    • replicasPerNodeGroup

      public final Integer replicasPerNodeGroup()

      An optional parameter that specifies the number of replica nodes in each node group (shard). Valid values are 0 to 5.

      Returns:
      An optional parameter that specifies the number of replica nodes in each node group (shard). Valid values are 0 to 5.

    • hasNodeGroupConfiguration

      public final boolean hasNodeGroupConfiguration()
      For responses, this returns true if the service returned a value for the NodeGroupConfiguration property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • nodeGroupConfiguration

      public final List<NodeGroupConfiguration> nodeGroupConfiguration()

      A list of node group (shard) configuration options. Each node group (shard) configuration has the following members: PrimaryAvailabilityZone, ReplicaAvailabilityZones, ReplicaCount, and Slots.

      If you're creating a Redis (cluster mode disabled) or a Redis (cluster mode enabled) replication group, you can use this parameter to individually configure each node group (shard), or you can omit this parameter. However, it is required when seeding a Redis (cluster mode enabled) cluster from a S3 rdb file. You must configure each node group (shard) using this parameter because you must specify the slots for each node group.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasNodeGroupConfiguration() method.

      Returns:
      A list of node group (shard) configuration options. Each node group (shard) configuration has the following members: PrimaryAvailabilityZone, ReplicaAvailabilityZones, ReplicaCount, and Slots.
