Class CreateClusterRequest

    • Method Detail

      • clusterName

        public final String clusterName()

        The cluster identifier. This parameter is stored as a lowercase string.

        Constraints:

        • A name must contain from 1 to 20 alphanumeric characters or hyphens.

        • The first character must be a letter.

        • A name cannot end with a hyphen or contain two consecutive hyphens.

        Returns:
        The cluster identifier. This parameter is stored as a lowercase string.

        Constraints:

        • A name must contain from 1 to 20 alphanumeric characters or hyphens.

        • The first character must be a letter.

        • A name cannot end with a hyphen or contain two consecutive hyphens.

      • nodeType

        public final String nodeType()

        The compute and memory capacity of the nodes in the cluster.

        Returns:
        The compute and memory capacity of the nodes in the cluster.

      • description

        public final String description()

        A description of the cluster.

        Returns:
        A description of the cluster.

      • replicationFactor

        public final Integer replicationFactor()

        The number of nodes in the DAX cluster. A replication factor of 1 will create a single-node cluster, without any read replicas. For additional fault tolerance, you can create a multiple node cluster with one or more read replicas. To do this, set ReplicationFactor to a number between 3 (one primary and two read replicas) and 10 (one primary and nine read replicas). If the AvailabilityZones parameter is provided, its length must equal the ReplicationFactor.

        AWS recommends that you have at least two read replicas per cluster.

        Returns:
        The number of nodes in the DAX cluster. A replication factor of 1 will create a single-node cluster, without any read replicas. For additional fault tolerance, you can create a multiple node cluster with one or more read replicas. To do this, set ReplicationFactor to a number between 3 (one primary and two read replicas) and 10 (one primary and nine read replicas). If the AvailabilityZones parameter is provided, its length must equal the ReplicationFactor.

        AWS recommends that you have at least two read replicas per cluster.

      • hasAvailabilityZones

        public final boolean hasAvailabilityZones()
        For responses, this returns true if the service returned a value for the AvailabilityZones 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.

      • availabilityZones

        public final List<String> availabilityZones()

        The Availability Zones (AZs) in which the cluster nodes will reside after the cluster has been created or updated. If provided, the length of this list must equal the ReplicationFactor parameter. If you omit this parameter, DAX will spread the nodes across Availability Zones for the highest availability.

        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 hasAvailabilityZones() method.

        Returns:
        The Availability Zones (AZs) in which the cluster nodes will reside after the cluster has been created or updated. If provided, the length of this list must equal the ReplicationFactor parameter. If you omit this parameter, DAX will spread the nodes across Availability Zones for the highest availability.

      • subnetGroupName

        public final String subnetGroupName()

        The name of the subnet group to be used for the replication group.

        DAX clusters can only run in an Amazon VPC environment. All of the subnets that you specify in a subnet group must exist in the same VPC.

        Returns:
        The name of the subnet group to be used for the replication group.

        DAX clusters can only run in an Amazon VPC environment. All of the subnets that you specify in a subnet group must exist in the same VPC.

      • hasSecurityGroupIds

        public final boolean hasSecurityGroupIds()
        For responses, this returns true if the service returned a value for the SecurityGroupIds 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.

      • securityGroupIds

        public final List<String> securityGroupIds()

        A list of security group IDs to be assigned to each node in the DAX cluster. (Each of the security group ID is system-generated.)

        If this parameter is not specified, DAX assigns the default VPC security group to each node.

        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 hasSecurityGroupIds() method.

        Returns:
        A list of security group IDs to be assigned to each node in the DAX cluster. (Each of the security group ID is system-generated.)

        If this parameter is not specified, DAX assigns the default VPC security group to each node.

      • preferredMaintenanceWindow

        public final String preferredMaintenanceWindow()

        Specifies the weekly time range during which maintenance on the DAX cluster is performed. It is specified as a range in the format ddd:hh24:mi-ddd:hh24:mi (24H Clock UTC). The minimum maintenance window is a 60 minute period. Valid values for ddd are:

        • sun

        • mon

        • tue

        • wed

        • thu

        • fri

        • sat

        Example: sun:05:00-sun:09:00

        If you don't specify a preferred maintenance window when you create or modify a cache cluster, DAX assigns a 60-minute maintenance window on a randomly selected day of the week.

        Returns:

        The Amazon SNS topic owner must be same as the DAX cluster owner.

        Returns:
        The Amazon Resource Name (ARN) of the Amazon SNS topic to which notifications will be sent.

        The Amazon SNS topic owner must be same as the DAX cluster owner.

      • iamRoleArn

        public final String iamRoleArn()

        A valid Amazon Resource Name (ARN) that identifies an IAM role. At runtime, DAX will assume this role and use the role's permissions to access DynamoDB on your behalf.

        Returns:

      • hasTags

        public final boolean hasTags()
        For responses, this returns true if the service returned a value for the Tags property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property).

      • clusterEndpointEncryptionTypeAsString

        public final String clusterEndpointEncryptionTypeAsString()

        The type of encryption the cluster's endpoint should support. Values are:

        • NONE for no encryption

        • TLS for Transport Layer Security

        If the service returns an enum value that is not available in the current SDK version, clusterEndpointEncryptionType will return ClusterEndpointEncryptionType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from clusterEndpointEncryptionTypeAsString().
