SageMaker Feature Store Adds UpdateRecord API

Amazon SageMaker Feature Store has been updated to support feature-level writes. The new UpdateRecord API enables the modification of one or more feature values within a record using a single API call. This eliminates the need to read and rewrite the entire record for updates, improving operational efficiency. The feature-level write capability is available for both the Standard online store tier, which utilizes Amazon DynamoDB, and the In-Memory online store tier, which uses Amazon ElastiCache. This update impacts users managing feature data within SageMaker Feature Store.
