  • Method Details

    • cacheClusterId

      public final String cacheClusterId()

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

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

    • numCacheNodes

      public final Integer numCacheNodes()

      The number of cache nodes that the cluster should have. If the value for NumCacheNodes is greater than the sum of the number of current cache nodes and the number of cache nodes pending creation (which may be zero), more nodes are added. If the value is less than the number of existing cache nodes, nodes are removed. If the value is equal to the number of current cache nodes, any pending add or remove requests are canceled.

      If you are removing cache nodes, you must use the CacheNodeIdsToRemove parameter to provide the IDs of the specific cache nodes to remove.

      For clusters running Redis, this value must be 1. For clusters running Memcached, this value must be between 1 and 40.

      Adding or removing Memcached cache nodes can be applied immediately or as a pending operation (see ApplyImmediately).

      A pending operation to modify the number of cache nodes in a cluster during its maintenance window, whether by adding or removing nodes in accordance with the scale out architecture, is not queued. The customer's latest request to add or remove nodes to the cluster overrides any previous pending operations to modify the number of cache nodes in the cluster. For example, a request to remove 2 nodes would override a previous pending operation to remove 3 nodes. Similarly, a request to add 2 nodes would override a previous pending operation to remove 3 nodes and vice versa. As Memcached cache nodes may now be provisioned in different Availability Zones with flexible cache node placement, a request to add nodes does not automatically override a previous pending operation to add nodes. The customer can modify the previous pending operation to add more nodes or explicitly cancel the pending request and retry the new request. To cancel pending operations to modify the number of cache nodes in a cluster, use the ModifyCacheCluster request and set NumCacheNodes equal to the number of cache nodes currently in the cluster.

      Returns:
      The number of cache nodes that the cluster should have. If the value for NumCacheNodes is greater than the sum of the number of current cache nodes and the number of cache nodes pending creation (which may be zero), more nodes are added. If the value is less than the number of existing cache nodes, nodes are removed. If the value is equal to the number of current cache nodes, any pending add or remove requests are canceled.

      If you are removing cache nodes, you must use the CacheNodeIdsToRemove parameter to provide the IDs of the specific cache nodes to remove.

    • hasCacheNodeIdsToRemove

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

    • cacheNodeIdsToRemove

      public final List<String> cacheNodeIdsToRemove()

      A list of cache node IDs to be removed. A node ID is a numeric identifier (0001, 0002, etc.). This parameter is only valid when NumCacheNodes is less than the existing number of cache nodes. The number of cache node IDs supplied in this parameter must match the difference between the existing number of cache nodes in the cluster or pending cache nodes, whichever is greater, and the value of NumCacheNodes in the request.

      For example: If you have 3 active cache nodes, 7 pending cache nodes, and the number of cache nodes in this ModifyCacheCluster call is 5, you must list 2 (7 - 5) cache node IDs to remove.

      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 hasCacheNodeIdsToRemove() method.

      Returns:
      A list of cache node IDs to be removed. A node ID is a numeric identifier (0001, 0002, etc.). This parameter is only valid when NumCacheNodes is less than the existing number of cache nodes. The number of cache node IDs supplied in this parameter must match the difference between the existing number of cache nodes in the cluster or pending cache nodes, whichever is greater, and the value of NumCacheNodes in the request.

      For example: If you have 3 active cache nodes, 7 pending cache nodes, and the number of cache nodes in this ModifyCacheCluster call is 5, you must list 2 (7 - 5) cache node IDs to remove.

    • azMode

      public final AZMode azMode()

      Specifies whether the new nodes in this Memcached cluster are all created in a single Availability Zone or created across multiple Availability Zones.

      Valid values: single-az | cross-az.

      This option is only supported for Memcached clusters.

      You cannot specify single-az if the Memcached cluster already has cache nodes in different Availability Zones. If cross-az is specified, existing Memcached nodes remain in their current Availability Zone.

      Only newly created nodes are located in different Availability Zones.

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

      Returns:
      Specifies whether the new nodes in this Memcached cluster are all created in a single Availability Zone or created across multiple Availability Zones.

      Valid values: single-az | cross-az.

      This option is only supported for Memcached clusters.

      You cannot specify single-az if the Memcached cluster already has cache nodes in different Availability Zones. If cross-az is specified, existing Memcached nodes remain in their current Availability Zone.

      Only newly created nodes are located in different Availability Zones.

    • hasNewAvailabilityZones

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

    • newAvailabilityZones

      public final List<String> newAvailabilityZones()

      This option is only supported on Memcached clusters.

      The list of Availability Zones where the new Memcached cache nodes are created.

      This parameter is only valid when NumCacheNodes in the request is greater than the sum of the number of active cache nodes and the number of cache nodes pending creation (which may be zero). The number of Availability Zones supplied in this list must match the cache nodes being added in this request.

      Scenarios:

      • Scenario 1: You have 3 active nodes and wish to add 2 nodes. Specify NumCacheNodes=5 (3 + 2) and optionally specify two Availability Zones for the two new nodes.

      • Scenario 2: You have 3 active nodes and 2 nodes pending creation (from the scenario 1 call) and want to add 1 more node. Specify NumCacheNodes=6 ((3 + 2) + 1) and optionally specify an Availability Zone for the new node.

      • Scenario 3: You want to cancel all pending operations. Specify NumCacheNodes=3 to cancel all pending operations.

      The Availability Zone placement of nodes pending creation cannot be modified. If you wish to cancel any nodes pending creation, add 0 nodes by setting NumCacheNodes to the number of current nodes.

      If cross-az is specified, existing Memcached nodes remain in their current Availability Zone. Only newly created nodes can be located in different Availability Zones. For guidance on how to move existing Memcached nodes to different Availability Zones, see the Availability Zone Considerations section of Cache Node Considerations for Memcached.

      Impact of new add/remove requests upon pending requests

      • Scenario-1

        • Pending Action: Delete

        • New Request: Delete

        • Result: The new delete, pending or immediate, replaces the pending delete.

      • Scenario-2

        • Pending Action: Delete

        • New Request: Create

        • Result: The new create, pending or immediate, replaces the pending delete.

      • Scenario-3

        • Pending Action: Create

        • New Request: Delete

        • Result: The new delete, pending or immediate, replaces the pending create.

      • Scenario-4

        • Pending Action: Create

        • New Request: Create

        • Result: The new create is added to the pending create.

          Important: If the new create request is Apply Immediately - Yes, all creates are performed immediately. If the new create request is Apply Immediately - No, all creates are pending.

      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 hasNewAvailabilityZones() method.

      Returns:

      This option is only supported on Memcached clusters.

      The list of Availability Zones where the new Memcached cache nodes are created.

      This parameter is only valid when NumCacheNodes in the request is greater than the sum of the number of active cache nodes and the number of cache nodes pending creation (which may be zero). The number of Availability Zones supplied in this list must match the cache nodes being added in this request.

      Scenarios:

      • Scenario 1: You have 3 active nodes and wish to add 2 nodes. Specify NumCacheNodes=5 (3 + 2) and optionally specify two Availability Zones for the two new nodes.

      public ModifyCacheClusterRequest.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<ModifyCacheClusterRequest.Builder,ModifyCacheClusterRequest>
      Specified by:
      toBuilder in class ElastiCacheRequest
      Returns:
      a builder for type T

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • 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:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)
      Description copied from class: SdkRequest
      Used to retrieve the value of a field from any class that extends SdkRequest. The field name specified should match the member name from the corresponding service-2.json model specified in the codegen-resources folder for a given service. The class specifies what class to cast the returned value to. If the returned value is also a modeled class, the SdkRequest.getValueForField(String, Class) method will again be available.
      Overrides:
      getValueForField in class SdkRequest
      Parameters:
      fieldName - The name of the member to be retrieved.
      clazz - The class to cast the returned object to.
      Returns:
      Optional containing the casted return value
