// TestFailover API operation for Amazon ElastiCache.
//
// 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).
//
// 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 AWS 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 AWS 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 master node <primary-node-id> to replica
//    node <node-id> completed
//
// Replication group message: Failover from master 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>

// The following node types are supported by ElastiCache. Generally speaking,

//
//    * General purpose:
//
// Current generation:
//
// T2 node types:cache.t2.micro, cache.t2.small, cache.t2.medium
//
// M3 node types:cache.m3.medium, cache.m3.large, cache.m3.xlarge, cache.m3.2xlarge

//
// Previous generation: (not recommended)
//
// T1 node types:cache.t1.micro
//
// M1 node types:cache.m1.small, cache.m1.medium, cache.m1.large, cache.m1.xlarge
//
//    * Compute optimized:
//
// Previous generation: (not recommended)
//
// C1 node types:cache.c1.xlarge
//
//    * Memory optimized:
//
// Current generation:
//
// R3 node types:cache.r3.large, cache.r3.xlarge, cache.r3.2xlarge, cache.r3.4xlarge,
//    cache.r3.8xlarge
//
// Previous generation: (not recommended)
//
// M2 node types:cache.m2.xlarge, cache.m2.2xlarge, cache.m2.4xlarge
//
// Notes:
//
//    * All T2 instances are created in an Amazon Virtual Private Cloud (Amazon

//
//    * Redis (cluster mode disabled): Redis backup/restore is not supported
