// Creates a recommender with the recipe (a Domain dataset group use case) you
// specify. You create recommenders for a Domain dataset group and specify the
// recommender's Amazon Resource Name (ARN) when you make a GetRecommendations (https://docs.aws.amazon.com/personalize/latest/dg/API_RS_GetRecommendations.html)
// request. Minimum recommendation requests per second A high
// minRecommendationRequestsPerSecond will increase your bill. We recommend
// starting with 1 for minRecommendationRequestsPerSecond (the default). Track
// your usage using Amazon CloudWatch metrics, and increase the
// minRecommendationRequestsPerSecond as necessary. When you create a recommender,
// you can configure the recommender's minimum recommendation requests per second.
// The minimum recommendation requests per second (
// minRecommendationRequestsPerSecond ) specifies the baseline recommendation
// request throughput provisioned by Amazon Personalize. The default
// minRecommendationRequestsPerSecond is 1 . A recommendation request is a single
// GetRecommendations operation. Request throughput is measured in requests per
// second and Amazon Personalize uses your requests per second to derive your
// requests per hour and the price of your recommender usage. If your requests per
// second increases beyond minRecommendationRequestsPerSecond , Amazon Personalize
// auto-scales the provisioned capacity up and down, but never below
// minRecommendationRequestsPerSecond . There's a short time delay while the
// capacity is increased that might cause loss of requests. Your bill is the
// greater of either the minimum requests per hour (based on
// minRecommendationRequestsPerSecond) or the actual number of requests. The actual
// request throughput used is calculated as the average requests/second within a
// one-hour window. We recommend starting with the default
// minRecommendationRequestsPerSecond , track your usage using Amazon CloudWatch
// metrics, and then increase the minRecommendationRequestsPerSecond as necessary.
// Status A recommender can be in one of the following states:
// - CREATE PENDING > CREATE IN_PROGRESS > ACTIVE -or- CREATE FAILED
// - STOP PENDING > STOP IN_PROGRESS > INACTIVE > START PENDING > START
// IN_PROGRESS > ACTIVE
// - DELETE PENDING > DELETE IN_PROGRESS
//
// To get the recommender status, call DescribeRecommender (https://docs.aws.amazon.com/personalize/latest/dg/API_DescribeRecommender.html)
// . Wait until the status of the recommender is ACTIVE before asking the
// recommender for recommendations. Related APIs
