Client for accessing Amazon ElastiCache. All service calls made using this client are blocking, and will not return until the service call completes.
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.

  - addTagsToResource
```
public AddTagsToResourceResult addTagsToResource(AddTagsToResourceRequest request)
```
    A tag is a key-value pair where the key and value are case-sensitive. You can use tags to categorize and track all your ElastiCache resources, with the exception of global replication group. When you add or remove tags on replication groups, those actions will be replicated to all nodes in the replication group. For more information, see Resource -level permissions.
    
    For example, you can use cost-allocation tags to your ElastiCache resources, Amazon 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.

```
public Snapshot copySnapshot(CopySnapshotRequest request)
```
    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.

  - createReplicationGroup
```
public ReplicationGroup createReplicationGroup(CreateReplicationGroupRequest request)
```
    Creates a Redis (cluster mode disabled) or a Redis (cluster mode enabled) replication group.
    
    This API can be used to create a standalone regional replication group or a secondary replication group associated with a Global datastore.
    
    A Redis (cluster mode disabled) replication group is a collection of clusters, where one of the 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 cluster is comprised of from 1 to 90 shards (API/CLI: node groups). Each shard has a primary node and up to 5 read-only replica nodes. The configuration can range from 90 shards and 0 replicas to 15 shards and 5 replicas, which is the maximum number or replicas allowed.
    
    The node or shard limit can be increased to a maximum of 500 per cluster if the Redis engine version is 5.0.6 or higher. For example, you can choose to configure a 500 node cluster that ranges between 83 shards (one primary and 5 replicas per shard) and 500 shards (single primary and no replicas). Make sure there are enough available IP addresses to accommodate the increase. Common pitfalls include the subnets in the subnet group have too small a CIDR range or the subnets are shared and heavily used by other clusters. For more information, see Creating a Subnet Group. For versions below 5.0.6, the limit is 250 per cluster.
    
    To request a limit increase, see Amazon Service Limits and choose the limit type Nodes per cluster per instance type.
    
    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. If you need to increase or decrease the number of node groups (console: shards), you can avail yourself of ElastiCache for Redis' scaling. For more information, see Scaling ElastiCache for Redis Clusters in the ElastiCache User Guide.
    
    This operation is valid for Redis only.

  - deleteGlobalReplicationGroup
```
public GlobalReplicationGroup deleteGlobalReplicationGroup(DeleteGlobalReplicationGroupRequest request)
```
    Deleting a Global datastore is a two-step process:
    - First, you must DisassociateGlobalReplicationGroup to remove the secondary clusters in the Global datastore.
    - Once the Global datastore contains only the primary cluster, you can use the DeleteGlobalReplicationGroup API to delete the Global datastore while retainining the primary cluster using RetainPrimaryReplicationGroup=true.
    Since the Global Datastore has only a primary cluster, you can delete the Global Datastore while retaining the primary by setting RetainPrimaryReplicationGroup=true. The primary cluster is never deleted when deleting a Global Datastore. It can only be deleted when it no longer is associated with any Global Datastore.
    
    When you receive a successful response from this operation, Amazon ElastiCache immediately begins deleting the selected resources; you cannot cancel or revert this operation.
    Specified by:
    
    deleteGlobalReplicationGroup in interface AmazonElastiCache
    
    Parameters:
    
    deleteGlobalReplicationGroupRequest -
    
    Returns:
    
    Result of the DeleteGlobalReplicationGroup operation returned by the service.
    
    Throws:
    
    GlobalReplicationGroupNotFoundException - The Global datastore does not exist
    
    InvalidGlobalReplicationGroupStateException - The Global datastore is not available or in primary-only state.
    
    InvalidParameterValueException - The value for a parameter is invalid.

  - deleteReplicationGroup
```
public ReplicationGroup deleteReplicationGroup(DeleteReplicationGroupRequest request)
```
    Deletes an existing replication group. By default, this operation deletes the entire replication group, including the primary/primaries and all of the read replicas. If the replication group has only one primary, you can optionally delete only the read replicas, while retaining the primary by setting RetainPrimaryCluster=true.
    
    When you receive a successful response from this operation, Amazon ElastiCache immediately begins deleting the selected resources; you cannot cancel or revert this operation.

  - rebootCacheCluster
```
public CacheCluster rebootCacheCluster(RebootCacheClusterRequest request)
```
    Reboots some, or all, of the cache nodes within a provisioned cluster. This operation applies any modified cache parameter groups to the cluster. The reboot operation takes place as soon as possible, and results in a momentary outage to the cluster. During the reboot, the cluster status is set to REBOOTING.

  - testFailover
```
public ReplicationGroup testFailover(TestFailoverRequest request)
```
    Represents the input of a TestFailover operation which test automatic failover on a specified node group (called shard in the console) in a replication group (called cluster in the console).
    
    This API is designed for testing the behavior of your application in case of ElastiCache failover. It is not designed to be an operational tool for initiating a failover to overcome a problem you may have with the cluster. Moreover, in certain conditions such as large-scale operational events, Amazon may block this API.
    
    Note the following
    - A customer can use this operation to test automatic failover on up to 5 shards (called node groups in the ElastiCache API and Amazon CLI) in any rolling 24-hour period.
    - If calling this operation on shards in different clusters (called replication groups in the API and CLI), the calls can be made concurrently.
    - If calling this operation multiple times on different shards in the same Redis (cluster mode enabled) replication group, the first node replacement must complete before a subsequent call can be made.
    - To determine whether the node replacement is complete you can check Events using the Amazon ElastiCache console, the Amazon CLI, or the ElastiCache API. Look for the following automatic failover related events, listed here in order of occurrance:
      
      Replication group message: Test Failover API called for node group <node-group-id>
      
      Cache cluster message: Failover from primary node <primary-node-id> to replica node <node-id> completed
      
      Replication group message: Failover from primary node <primary-node-id> to replica node <node-id> completed
      
      Cache cluster message: Recovering cache nodes <node-id>
      
      Cache cluster message: Finished recovery for cache nodes <node-id>

  - getCachedResponseMetadata
```
public 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 the request.
    
    Specified by:
    
    getCachedResponseMetadata in interface AmazonElastiCache
    
    Parameters:
    
    request - The originally executed request
