 ** enableMetadataWithRecommendations **   <a name="personalize-Type-RecommenderConfig-enableMetadataWithRecommendations"></a>
Whether metadata with recommendations is enabled for the recommender. If enabled, you can specify the columns from your Items dataset in your request for recommendations. Amazon Personalize returns this data for each item in the recommendation response. For information about enabling metadata for a recommender, see [Enabling metadata in recommendations for a recommender](https://docs.aws.amazon.com/personalize/latest/dg/creating-recommenders.html#create-recommender-return-metadata).  
 If you enable metadata in recommendations, you will incur additional costs. For more information, see [Amazon Personalize pricing](https://aws.amazon.com/personalize/pricing/).

Provide `itemExplorationConfig` data only if your recommenders generate personalized recommendations for a user (not popular items or similar items).

 ** minRecommendationRequestsPerSecond **   <a name="personalize-Type-RecommenderConfig-minRecommendationRequestsPerSecond"></a>
