// 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 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
