-- 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
-- <https://docs.aws.amazon.com/personalize/latest/dg/API_RS_GetRecommendations.html GetRecommendations>
-- 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
-- <https://docs.aws.amazon.com/personalize/latest/dg/API_DescribeRecommender.html DescribeRecommender>.
--
-- Wait until the @status@ of the recommender is @ACTIVE@ before asking the
-- recommender for recommendations.
