 * <fullname>Amazon ElastiCache</fullname>
 * <p>
 * Amazon ElastiCache is a web service that makes it easier to set up, operate, and scale a distributed cache in the
 * cloud.
 * </p>
 * <p>
 * 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.
 * </p>
 * <p>
 * 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.
 * </p>

     * <p>
     * Creates a Redis (cluster mode disabled) or a Redis (cluster mode enabled) replication group.
     * </p>
     * <p>
     * This API can be used to create a standalone regional replication group or a secondary replication group
     * associated with a Global datastore.
     * </p>
     * <p>
     * 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.
     * </p>
     * <p>
     * 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.
     * </p>
     * <p>
     * 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 <a
     * href="https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/SubnetGroups.Creating.html">Creating a Subnet
     * Group</a>. For versions below 5.0.6, the limit is 250 per cluster.
     * </p>
     * <p>
     * To request a limit increase, see <a
     * href="https://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html">Amazon Service Limits</a> and choose
     * the limit type <b>Nodes per cluster per instance type</b>.
     * </p>
     * <p>
     * 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 <a
     * href="https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Scaling.html">Scaling ElastiCache for Redis

     * <p>
     * Represents the input of a <code>TestFailover</code> operation which test automatic failover on a specified node
     * group (called shard in the console) in a replication group (called cluster in the console).
     * </p>
     * <p>
     * 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.
     * </p>
     * <p class="title">
     * <b>Note the following</b>
     * </p>
     * <ul>
     * <li>
     * <p>
     * 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.
     * </p>
     * </li>
     * <li>
     * <p>
     * If calling this operation on shards in different clusters (called replication groups in the API and CLI), the
     * calls can be made concurrently.
     * </p>
     * <p>
     * </p></li>
     * <li>
     * <p>
     * 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.
     * </p>
     * </li>
     * <li>
     * <p>
     * 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
