Class ModifyReplicationGroupShardConfigurationRequest

    • Method Detail

      • replicationGroupId

        public final String replicationGroupId()

        The name of the Redis (cluster mode enabled) cluster (replication group) on which the shards are to be configured.

        Returns:
        The name of the Redis (cluster mode enabled) cluster (replication group) on which the shards are to be configured.
      • nodeGroupCount

        public final Integer nodeGroupCount()

        The number of node groups (shards) that results from the modification of the shard configuration.

        Returns:
        The number of node groups (shards) that results from the modification of the shard configuration.
      • applyImmediately

        public final Boolean applyImmediately()

        Indicates that the shard reconfiguration process begins immediately. At present, the only permitted value for this parameter is true.

        Value: true

        Returns:
        Indicates that the shard reconfiguration process begins immediately. At present, the only permitted value for this parameter is true.

        Value: true

      • hasReshardingConfiguration

        public final boolean hasReshardingConfiguration()
        For responses, this returns true if the service returned a value for the ReshardingConfiguration 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.
      • reshardingConfiguration

        public final List<ReshardingConfiguration> reshardingConfiguration()

        Specifies the preferred availability zones for each node group in the cluster. If the value of NodeGroupCount is greater than the current number of node groups (shards), you can use this parameter to specify the preferred availability zones of the cluster's shards. If you omit this parameter ElastiCache selects availability zones for you.

        You can specify this parameter only if the value of NodeGroupCount is greater than the current number of node groups (shards).

        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 hasReshardingConfiguration() method.

        Returns:
        Specifies the preferred availability zones for each node group in the cluster. If the value of NodeGroupCount is greater than the current number of node groups (shards), you can use this parameter to specify the preferred availability zones of the cluster's shards. If you omit this parameter ElastiCache selects availability zones for you.

        You can specify this parameter only if the value of NodeGroupCount is greater than the current number of node groups (shards).

      • hasNodeGroupsToRemove

        public final boolean hasNodeGroupsToRemove()
        For responses, this returns true if the service returned a value for the NodeGroupsToRemove 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.
      • nodeGroupsToRemove

        public final List<String> nodeGroupsToRemove()

        If the value of NodeGroupCount is less than the current number of node groups (shards), then either NodeGroupsToRemove or NodeGroupsToRetain is required. NodeGroupsToRemove is a list of NodeGroupIds to remove from the cluster.

        ElastiCache for Redis will attempt to remove all node groups listed by NodeGroupsToRemove from the cluster.

        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 hasNodeGroupsToRemove() method.

        Returns:
        If the value of NodeGroupCount is less than the current number of node groups (shards), then either NodeGroupsToRemove or NodeGroupsToRetain is required. NodeGroupsToRemove is a list of NodeGroupIds to remove from the cluster.

        ElastiCache for Redis will attempt to remove all node groups listed by NodeGroupsToRemove from the cluster.

      • hasNodeGroupsToRetain

        public final boolean hasNodeGroupsToRetain()
        For responses, this returns true if the service returned a value for the NodeGroupsToRetain 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.
      • nodeGroupsToRetain

        public final List<String> nodeGroupsToRetain()

        If the value of NodeGroupCount is less than the current number of node groups (shards), then either NodeGroupsToRemove or NodeGroupsToRetain is required. NodeGroupsToRetain is a list of NodeGroupIds to retain in the cluster.

        ElastiCache for Redis will attempt to remove all node groups except those listed by NodeGroupsToRetain from the cluster.

        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 hasNodeGroupsToRetain() method.

        Returns:
        If the value of NodeGroupCount is less than the current number of node groups (shards), then either NodeGroupsToRemove or NodeGroupsToRetain is required. NodeGroupsToRetain is a list of NodeGroupIds to retain in the cluster.

        ElastiCache for Redis will attempt to remove all node groups except those listed by NodeGroupsToRetain from the cluster.

      • toString

        public final String toString()
        Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
        Overrides:
