```
      A name for the snapshot copy. ElastiCache does not permit overwriting a snapshot, therefore this name must be unique within its context - ElastiCache or an Amazon S3 bucket if exporting.
      
      Error Message
      
      Error Message: The S3 bucket %s already contains an object with key %s.
      
      Solution: Give the TargetSnapshotName a new and unique value. If exporting a snapshot, you could alternatively create a new Amazon S3 bucket and use this same value for TargetSnapshotName.
    - targetBucket
```
String targetBucket
```
      The Amazon S3 bucket to which the snapshot will be exported. This parameter is used only when exporting a snapshot for external access.
      
      When using this parameter to export a snapshot, be sure Amazon ElastiCache has the needed permissions to this S3 bucket. For more information, see Step 2: Grant ElastiCache Access to Your Amazon S3 Bucket in the Amazon ElastiCache User Guide.
      
      Error Messages:
      
      You could receive one of the following error messages.
      
      Erorr Messages
      
      Error Message: ElastiCache has not been granted READ permissions %s on the S3 Bucket.
      
      Solution: Add List and Read permissions on the bucket.
      
      Error Message: ElastiCache has not been granted WRITE permissions %s on the S3 Bucket.
      
      Solution: Add Upload/Delete permissions on the bucket.
      
      Error Message: ElastiCache has not been granted READ_ACP permissions %s on the S3 Bucket.
      
      Solution: Add View Permissions permissions on the bucket.
      
      Error Message: The S3 bucket %s is outside of the region.
      
      Solution: Before exporting your snapshot, create a new Amazon S3 bucket in the same region as your snapshot. For more information, see Step 1: Create an Amazon S3 Bucket.
      
      Error Message: The S3 bucket %s does not exist.
      
      Solution: Create an Amazon S3 bucket in the same region as your snapshot. For more information, see Step 1: Create an Amazon S3 Bucket.
      
      Error Message: The S3 bucket %s is not owned by the authenticated user.
      
      Solution: Create an Amazon S3 bucket in the same region as your snapshot. For more information, see Step 1: Create an Amazon S3 Bucket.
      
      Error Message: The authenticated user does not have sufficient permissions to perform the desired activity.
      
      Solution: Contact your system administrator to get the needed permissions.
      
      For more information, see Exporting a Snapshot in the Amazon ElastiCache User Guide.
- Class com.amazonaws.services.elasticache.model.CreateCacheClusterRequest extends AmazonWebServiceRequest implements Serializable
  - Serialized Fields
    - cacheClusterId
```
String cacheClusterId
```
      The node group 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.
    - replicationGroupId
```
String replicationGroupId
```
      The ID of the replication group to which this cache cluster should belong. If this parameter is specified, the cache cluster will be added to the specified replication group as a read replica; otherwise, the cache cluster will be a standalone primary that is not part of any replication group.
      
      If the specified replication group is Multi-AZ enabled and the availability zone is not specified, the cache cluster will be created in availability zones that provide the best spread of read replicas across availability zones.
      
      This parameter is only valid if the Engine parameter is redis.
    - aZMode
```
String aZMode
```
      Specifies whether the nodes in this Memcached node group are created in a single Availability Zone or created across multiple Availability Zones in the cluster's region.
      
      This parameter is only supported for Memcached cache clusters.
      
      If the AZMode and PreferredAvailabilityZones are not specified, ElastiCache assumes single-az mode.
    - preferredAvailabilityZone
```
String preferredAvailabilityZone
```
      The EC2 Availability Zone in which the cache cluster will be created.
      
      All nodes belonging to this Memcached cache cluster are placed in the preferred Availability Zone. If you want to create your nodes across multiple Availability Zones, use PreferredAvailabilityZones.
      
      Default: System chosen Availability Zone.
    - preferredAvailabilityZones
```
com.amazonaws.internal.SdkInternalList<T> preferredAvailabilityZones
```
      A list of the Availability Zones in which cache nodes will be created. The order of the zones in the list is not important.
      
      This option is only supported on Memcached.
      
      If you are creating your cache cluster in an Amazon VPC (recommended) you can only locate nodes in Availability Zones that are associated with the subnets in the selected subnet group.
      
      The number of Availability Zones listed must equal the value of NumCacheNodes.
      
      If you want all the nodes in the same Availability Zone, use PreferredAvailabilityZone instead, or repeat the Availability Zone multiple times in the list.
      
      Default: System chosen Availability Zones.
      
      Example: One Memcached node in each of three different Availability Zones: PreferredAvailabilityZones.member.1=us-west-2a&PreferredAvailabilityZones.member.2=us-west-2b&PreferredAvailabilityZones.member.3=us-west-2c
      
      Example: All three Memcached nodes in one Availability Zone: PreferredAvailabilityZones.member.1=us-west-2a&PreferredAvailabilityZones.member.2=us-west-2a&PreferredAvailabilityZones.member.3=us-west-2a
    - numCacheNodes
```
Integer numCacheNodes
```
      The initial number of cache nodes that the cache cluster will have.
      
      For clusters running Redis, this value must be 1. For clusters running Memcached, this value must be between 1 and 20.
      
      If you need more than 20 nodes for your Memcached cluster, please fill out the ElastiCache Limit Increase Request form at http://aws.amazon.com/contact-us/elasticache-node-limit-request/.
    - cacheNodeType
```
String cacheNodeType
```
      The compute and memory capacity of the nodes in the node group.
      
      Valid node types are as follows:
      
      General purpose:
      
      Current generation: cache.t2.micro, cache.t2.small, cache.t2.medium, cache.m3.medium, cache.m3.large, cache.m3.xlarge, cache.m3.2xlarge
      
      Previous generation: cache.t1.micro, cache.m1.small, cache.m1.medium, cache.m1.large, cache.m1.xlarge

String cacheClusterId
```
      The name of the cache cluster you want to scale up to a larger node instanced type. ElastiCache uses the cluster id to identify the current node type of this cluster and from that to to create a list of node types you can scale up to.
      
      You must provide a value for either the CacheClusterId or the ReplicationGroupId.
    - replicationGroupId
```
String replicationGroupId
```
      The name of the replication group want to scale up to a larger node type. ElastiCache uses the replication group id to identify the current node type being used by this replication group, and from that to create a list of node types you can scale up to.
      
      You must provide a value for either the CacheClusterId or the ReplicationGroupId.
- Class com.amazonaws.services.elasticache.model.ListAllowedNodeTypeModificationsResult extends Object implements Serializable

    - scaleUpModifications
```
com.amazonaws.internal.SdkInternalList<T> scaleUpModifications
```
      A string list, each element of which specifies a cache node type which you can use to scale your cache cluster or replication group.
      
      When scaling up a Redis cluster or replication group using ModifyCacheCluster or ModifyReplicationGroup, use a value from this list for the CacheNodeType parameter.
- Class com.amazonaws.services.elasticache.model.ListTagsForResourceRequest extends AmazonWebServiceRequest implements Serializable

      A list of cost allocation tags as key-value pairs.
- Class com.amazonaws.services.elasticache.model.ModifyCacheClusterRequest extends AmazonWebServiceRequest implements Serializable
  - Serialized Fields
    - cacheClusterId
```
String cacheClusterId
```
      The cache cluster identifier. This value is stored as a lowercase string.
    - numCacheNodes
```
Integer numCacheNodes
```
      The number of cache nodes that the cache 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), then more nodes will be added. If the value is less than the number of existing cache nodes, then nodes will be removed. If the value is equal to the number of current cache nodes, then 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 20.
      
      Adding or removing Memcached cache nodes can be applied immediately or as a pending action. See ApplyImmediately.
      
      A pending action 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 actions to modify the number of cache nodes in the cluster. For example, a request to remove 2 nodes would override a previous pending action to remove 3 nodes. Similarly, a request to add 2 nodes would override a previous pending action 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 action to add nodes. The customer can modify the previous pending action to add more nodes or explicitly cancel the pending request and retry the new request. To cancel pending actions 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 cache cluster.
    - cacheNodeIdsToRemove
```
com.amazonaws.internal.SdkInternalList<T> 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 ModifyCacheCluser call is 5, you must list 2 (7 - 5) cache node IDs to remove.
    - aZMode
```
String aZMode
```
      Specifies whether the new nodes in this Memcached cache 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 cache clusters.
      
      You cannot specify single-az if the Memcached cache 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 will be located in different Availability Zones. For instructions on how to move existing Memcached nodes to different Availability Zones, see the Availability Zone Considerations section of Cache Node Considerations for Memcached.
    - newAvailabilityZones
```
com.amazonaws.internal.SdkInternalList<T> newAvailabilityZones
```
      The list of Availability Zones where the new Memcached cache nodes will be 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.
      
      This option is only supported on Memcached clusters.
      
      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 actions. Specify NumCacheNodes=3 to cancel all pending actions.
      
      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.
      
      Example:

    - numCacheNodes
```
Integer numCacheNodes
```
      The number of cache nodes in the source cache cluster.
      
      For clusters running Redis, this value must be 1. For clusters running Memcached, this value must be between 1 and 20.
    - preferredAvailabilityZone
```
String preferredAvailabilityZone
```
      The name of the Availability Zone in which the source cache cluster is located.
    - cacheClusterCreateTime
```
Date cacheClusterCreateTime
```
      The date and time when the source cache cluster was created.
    - preferredMaintenanceWindow
```
String preferredMaintenanceWindow
```
      Specifies the weekly time range during which maintenance on the cache 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
    - topicArn
```

```
      The Amazon Resource Name (ARN) for the topic used by the source cache cluster for publishing notifications.
    - port
```
Integer port
```
      The port number used by each cache nodes in the source cache cluster.
    - cacheParameterGroupName
```
String cacheParameterGroupName
```

```
Boolean autoMinorVersionUpgrade
```
      This parameter is currently disabled.
    - snapshotRetentionLimit
```
Integer snapshotRetentionLimit
```
      For an automatic snapshot, the number of days for which ElastiCache will retain the snapshot before deleting it.
      
      For manual snapshots, this field reflects the SnapshotRetentionLimit for the source cache cluster when the snapshot was created. This field is otherwise ignored: Manual snapshots do not expire, and can only be deleted using the DeleteSnapshot action.
      
      Important If the value of SnapshotRetentionLimit is set to zero (0), backups are turned off.
