/AWS1/CL_PZZ=>CREATERECOMMENDER()¶
About CreateRecommender¶
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 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.
Wait until the status of the recommender
is ACTIVE before asking the recommender for recommendations.
