    <description>

      <para>Adds up to 50 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 <a href="https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Tagging.html">Using Cost Allocation Tags in Amazon ElastiCache</a> in the <i>ElastiCache User Guide</i>. </para>

          <description>

            <para>The number of cache nodes that the cluster should have. If the value for <code>NumCacheNodes</code> 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 <code>CacheNodeIdsToRemove</code> 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 operation (see <code>ApplyImmediately</code>). 

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 <code>ModifyCacheCluster</code> request and set <code>NumCacheNodes</code> equal to the number of cache nodes currently in the cluster. </para>

        <description>

          <para>The number of cache nodes that the cluster should have. If the value for <code>NumCacheNodes</code> 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 <code>CacheNodeIdsToRemove</code> 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 operation (see <code>ApplyImmediately</code>). 

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 <code>ModifyCacheCluster</code> request and set <code>NumCacheNodes</code> equal to the number of cache nodes currently in the cluster. </para>

      <para>Returns information about all provisioned clusters if no cluster identifier is specified, or about a specific cache cluster if a cluster identifier is supplied. 

By default, abbreviated information about the clusters is returned. You can use the optional <i>ShowCacheNodeInfo</i> flag to retrieve detailed information about the cache nodes associated with the clusters. These details include the DNS address and port for the cache node endpoint. 

If the cluster is in the <i>creating</i> state, only cluster-level information is displayed until all of the nodes are successfully provisioned. 

If the cluster is in the <i>deleting</i> state, only cluster-level information is displayed. 

If cache nodes are currently being added to the cluster, node endpoint information and creation time for the additional nodes are not displayed until they are completely provisioned. When the cluster state is <i>available</i>, the cluster is ready for use. 

If cache nodes are currently being removed from the cluster, no endpoint information for the removed nodes is displayed. 

<br /><br />This operation automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. </para>

      <para>Returns events related to clusters, cache security groups, and cache parameter groups. You can obtain events specific to a particular cluster, cache security group, or cache parameter group by providing the name as a parameter. 

By default, only the events occurring within the last hour are returned; however, you can retrieve up to 14 days' worth of events if necessary. 

<br /><br />This operation automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. </para>

      <para>Lists all cost allocation tags currently on the named resource. A <code>cost allocation tag</code> is a key-value pair where the key is case-sensitive and the value is optional. You can use cost allocation tags to categorize and track your AWS costs. 

If the cluster is not in the <i>available</i> state, <code>ListTagsForResource</code> returns an error. 

You can have a maximum of 50 cost allocation tags on an ElastiCache resource. For more information, see <a href="https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Tagging.html">Monitoring Costs with Tags</a>. </para>

      <para>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 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) replication group is a collection of 1 to 90 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. However, if you need to increase or decrease the number of node groups (console: shards), you can avail yourself of ElastiCache for Redis' enhanced backup and restore. For more information, see <a href="https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/backups-restoring.html">Restoring From a Backup with Cluster Resizing</a> in the <i>ElastiCache User Guide</i>. 

This operation is valid for Redis only. </para>

This parameter is valid only if the <code>Engine</code> parameter is <code>redis</code>, the <code>EngineVersion</code> parameter is <code>3.2.6</code>, <code>4.x</code> or later, and the cluster is being created in an Amazon VPC. 

If you enable in-transit encryption, you must also specify a value for <code>CacheSubnetGroup</code>. 

<b>Required:</b> Only available when creating a replication group in an Amazon VPC using redis version <code>3.2.6</code>, <code>4.x</code> or later. 

Default: <code>false</code> <important><para>For HIPAA compliance, you must specify <code>TransitEncryptionEnabled</code> as <code>true</code>, an <code>AuthToken</code>, and a <code>CacheSubnetGroup</code>.</para></important> </para>

      <para>Deletes a previously provisioned cluster. <code>DeleteCacheCluster</code> deletes all associated cache nodes, node endpoints and the cluster itself. When you receive a successful response from this operation, Amazon ElastiCache immediately begins deleting the cluster; you cannot cancel or revert this operation. 

This operation is not valid for: 

 - 

Redis (cluster mode enabled) clusters 

 - 

A cluster that is the last read replica of a replication group 

 - 

A node group (shard) that has Multi-AZ mode enabled 

 - 

A cluster from a Redis (cluster mode enabled) replication group 

 - 

A cluster that is not in the <code>available</code> state </para>

      <para>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 <code>RetainPrimaryCluster=true</code>. 

When you receive a successful response from this operation, Amazon ElastiCache immediately begins deleting the selected resources; you cannot cancel or revert this operation. 

This operation is valid for Redis only. </para>

            <para>The number of read replica nodes you want at the completion of this operation. For Redis (cluster mode disabled) replication groups, this is the number of replica nodes in the replication group. For Redis (cluster mode enabled) replication groups, this is the number of replica nodes in each of the replication group's node groups. 

The minimum number of replicas in a shard or replication group is: 

 - Redis (cluster mode disabled) 

 - If Multi-AZ with Automatic Failover is enabled: 1 

 - If Multi-AZ with Automatic Failover is not enabled: 0 

 - Redis (cluster mode enabled): 0 (though you will not be able to failover to a replica if your primary node fails) </para>

    <description>

      <para>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. 

The reboot causes the contents of the cache (for each cache node being rebooted) to be lost. 

When the reboot is complete, a cluster event is created. 

Rebooting a cluster is currently supported on Memcached and Redis (cluster mode disabled) clusters. Rebooting is not supported on Redis (cluster mode enabled) clusters. 

If you make changes to parameters that require a Redis (cluster mode enabled) cluster reboot for the changes to be applied, see <a href="http://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Clusters.Rebooting.html">Rebooting a Cluster</a> for an alternate process. </para>
