Interface for accessing Amazon ElastiCache.
Note: Do not directly implement this interface, new methods are added to it regularly. Extend from AbstractAmazonElastiCache instead.

Amazon ElastiCache
Amazon ElastiCache is a web service that makes it easier to set up, operate, and scale a distributed cache in the cloud.

With ElastiCache, customers get all of the benefits of a high-performance, in-memory cache with less of the administrative burden involved in launching and managing a distributed cache. The service makes setup, scaling, and cluster failure handling much simpler than in a self-managed cache deployment.

In addition, through integration with Amazon CloudWatch, customers get enhanced visibility into the key performance statistics associated with their cache and can receive alarms if a part of their cache runs hot.

- Field Detail
  - ENDPOINT_PREFIX
```
static final String ENDPOINT_PREFIX
```
    The region metadata service name for computing region endpoints. You can use this value to retrieve metadata (such as supported regions) of the service.
    
    See Also:
    
    RegionUtils.getRegionsForService(String), Constant Field Values
- Method Detail
  - setEndpoint
```
@Deprecated
void setEndpoint(String endpoint)
```
    Deprecated. use AwsClientBuilder#setEndpointConfiguration(AwsClientBuilder.EndpointConfiguration) for example: builder.setEndpointConfiguration(new EndpointConfiguration(endpoint, signingRegion));
    
    Overrides the default endpoint for this client ("elasticache.us-east-1.amazonaws.com"). Callers can use this method to control which AWS region they want to work with.
    Callers can pass in just the endpoint (ex: "elasticache.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "elasticache.us-east-1.amazonaws.com"). If the protocol is not specified here, the default protocol from this client's ClientConfiguration will be used, which by default is HTTPS.
    For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: http://developer.amazonwebservices.com/connect/entry.jspa?externalID=3912
    This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.
    
    Parameters:
    
    endpoint - The endpoint (ex: "elasticache.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "elasticache.us-east-1.amazonaws.com") of the region specific AWS endpoint this client will communicate with.
  - setRegion
```
@Deprecated
void setRegion(Region region)
```
    Deprecated. use AwsClientBuilder#setRegion(String)
    
    An alternative to setEndpoint(String), sets the regional endpoint for this client's service calls. Callers can use this method to control which AWS region they want to work with.
    By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the ClientConfiguration supplied at construction.
    This method is not threadsafe. A region should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.
    
    Parameters:
    
    region - The region this client will communicate with. See Region.getRegion(com.amazonaws.regions.Regions) for accessing a given region. Must not be null and must be a region where the service is available.
    
    See Also:
    
    Region.getRegion(com.amazonaws.regions.Regions), Region.createClient(Class, com.amazonaws.auth.AWSCredentialsProvider, ClientConfiguration), Region.isServiceSupported(String)
  - addTagsToResource
```
AddTagsToResourceResult addTagsToResource(AddTagsToResourceRequest addTagsToResourceRequest)
```
    Adds up to 10 cost allocation tags to the named resource. A cost allocation tag is a key-value pair where the key and value are case-sensitive. You can use cost allocation tags to categorize and track your AWS costs.
    
    When you apply tags to your ElastiCache resources, AWS generates a cost allocation report as a comma-separated value (CSV) file with your usage and costs aggregated by your tags. You can apply tags that represent business categories (such as cost centers, application names, or owners) to organize your costs across multiple services. For more information, see Using Cost Allocation Tags in Amazon ElastiCache in the ElastiCache User Guide.
    
    Parameters:
    
    addTagsToResourceRequest - Represents the input of an AddTagsToResource operation.
    
    Returns:
    
    Result of the AddTagsToResource operation returned by the service.
    
    Throws:
    
    CacheClusterNotFoundException - The requested cache cluster ID does not refer to an existing cache cluster.
    
    SnapshotNotFoundException - The requested snapshot name does not refer to an existing snapshot.
    
    TagQuotaPerResourceExceededException - The request cannot be processed because it would cause the resource to have more than the allowed number of tags. The maximum number of tags permitted on a resource is 10.
    
    InvalidARNException - The requested Amazon Resource Name (ARN) does not refer to an existing resource.

  - authorizeCacheSecurityGroupIngress
```
CacheSecurityGroup authorizeCacheSecurityGroupIngress(AuthorizeCacheSecurityGroupIngressRequest authorizeCacheSecurityGroupIngressRequest)
```
    Allows network ingress to a cache security group. Applications using ElastiCache must be running on Amazon EC2, and Amazon EC2 security groups are used as the authorization mechanism.
    
    You cannot authorize ingress from an Amazon EC2 security group in one region to an ElastiCache cluster in another region.
    
    Parameters:
    
    authorizeCacheSecurityGroupIngressRequest - Represents the input of an AuthorizeCacheSecurityGroupIngress operation.
    
    Returns:
    
    Result of the AuthorizeCacheSecurityGroupIngress operation returned by the service.
    
    Throws:
    
    CacheSecurityGroupNotFoundException - The requested cache security group name does not refer to an existing cache security group.
    
    InvalidCacheSecurityGroupStateException - The current state of the cache security group does not allow deletion.
    
    AuthorizationAlreadyExistsException - The specified Amazon EC2 security group is already authorized for the specified cache security group.
    
    InvalidParameterValueException - The value for a parameter is invalid.
    
    InvalidParameterCombinationException - Two or more incompatible parameters were specified.

  - copySnapshot
```
Snapshot copySnapshot(CopySnapshotRequest copySnapshotRequest)
```
    Makes a copy of an existing snapshot.
    
    This operation is valid for Redis only.
    
    Users or groups that have permissions to use the CopySnapshot operation can create their own Amazon S3 buckets and copy snapshots to it. To control access to your snapshots, use an IAM policy to control who has the ability to use the CopySnapshot operation. For more information about using IAM to control the use of ElastiCache operations, see Exporting Snapshots and Authentication & Access Control.
    
    You could receive the following error messages.
    
    Error Messages
    - Error Message: The S3 bucket %s is outside of the region.
      
      Solution: Create an Amazon S3 bucket in the same region as your snapshot. For more information, see Step 1: Create an Amazon S3 Bucket in the ElastiCache User Guide.
    - 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 in the ElastiCache User Guide.
    - 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 in the ElastiCache User Guide.
    - 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.
    - 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.
    - Error Message: ElastiCache has not been granted READ permissions %s on the S3 Bucket.
      
      Solution: Add List and Read permissions on the bucket. For more information, see Step 2: Grant ElastiCache Access to Your Amazon S3 Bucket in the ElastiCache User Guide.
    - Error Message: ElastiCache has not been granted WRITE permissions %s on the S3 Bucket.
      
      Solution: Add Upload/Delete permissions on the bucket. For more information, see Step 2: Grant ElastiCache Access to Your Amazon S3 Bucket in the ElastiCache User Guide.
    - Error Message: ElastiCache has not been granted READ_ACP permissions %s on the S3 Bucket.

  - createReplicationGroup
```
ReplicationGroup createReplicationGroup(CreateReplicationGroupRequest createReplicationGroupRequest)
```
    Creates a Redis (cluster mode disabled) or a Redis (cluster mode enabled) replication group.
    
    A Redis (cluster mode disabled) replication group is a collection of cache clusters, where one of the cache clusters is a read/write primary and the others are read-only replicas. Writes to the primary are asynchronously propagated to the replicas.
    
    A Redis (cluster mode enabled) replication group is a collection of 1 to 15 node groups (shards). Each node group (shard) has one read/write primary node and up to 5 read-only replica nodes. Writes to the primary are asynchronously propagated to the replicas. Redis (cluster mode enabled) replication groups partition the data across node groups (shards).
    
    When a Redis (cluster mode disabled) replication group has been successfully created, you can add one or more read replicas to it, up to a total of 5 read replicas. You cannot alter a Redis (cluster mode enabled) replication group after it has been created.

  - rebootCacheCluster
```
CacheCluster rebootCacheCluster(RebootCacheClusterRequest rebootCacheClusterRequest)
```
    Reboots some, or all, of the cache nodes within a provisioned cache cluster. This operation applies any modified cache parameter groups to the cache cluster. The reboot operation takes place as soon as possible, and results in a momentary outage to the cache cluster. During the reboot, the cache cluster status is set to REBOOTING.
    
    The reboot causes the contents of the cache (for each cache node being rebooted) to be lost.
    
    When the reboot is complete, a cache cluster event is created.
    
    Parameters:
    
    rebootCacheClusterRequest - Represents the input of a RebootCacheCluster operation.
    
    Returns:
    
    Result of the RebootCacheCluster operation returned by the service.
    
    Throws:
    
    InvalidCacheClusterStateException - The requested cache cluster is not in the available state.
    
    CacheClusterNotFoundException - The requested cache cluster ID does not refer to an existing cache cluster.

    resetCacheParameterGroupRequest - Represents the input of a ResetCacheParameterGroup operation.
    
    Returns:
    
    Result of the ResetCacheParameterGroup operation returned by the service.
    
    Throws:
    
    InvalidCacheParameterGroupStateException - The current state of the cache parameter group does not allow the requested operation to occur.
    
    CacheParameterGroupNotFoundException - The requested cache parameter group name does not refer to an existing cache parameter group.

  - revokeCacheSecurityGroupIngress
```
CacheSecurityGroup revokeCacheSecurityGroupIngress(RevokeCacheSecurityGroupIngressRequest revokeCacheSecurityGroupIngressRequest)
```
    Revokes ingress from a cache security group. Use this operation to disallow access from an Amazon EC2 security group that had been previously authorized.
    
    Parameters:
    
    revokeCacheSecurityGroupIngressRequest - Represents the input of a RevokeCacheSecurityGroupIngress operation.

  - shutdown
```
void shutdown()
```
    Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.
  - getCachedResponseMetadata
```
ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
```
    Returns additional metadata for a previously executed successful request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.
    Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing a request.
    
    Parameters:
    
    request - The originally executed request.
    
    Returns:
    
    The response metadata for the specified request, or null if none is available.
