NEW
An AWS-managed feature store for storing, sharing, and serving machine learning features for training and inference.
DESCRIPTION
Amazon SageMaker Feature Store centralizes the creation, storage, discovery, and serving of ML features. It provides an offline store for batch training and an online store for low-latency inference. Integrated with SageMaker pipelines, it supports feature versioning, lineage, and access controls. Teams use it to reduce duplication, ensure consistency between training and serving, and accelerate model deployment. It fits into MLOps workflows with monitoring and governance capabilities on AWS.
