Amazon SageMaker Feature Store serves as a dedicated, fully managed repository designed to store, share, and oversee features essential for machine learning (ML) models. These features function as the inputs for ML models during both the training phase and inference process. For instance, in a music recommendation application, relevant features might encompass song ratings, duration of listening, and demographic information about the listeners. The ability to reuse features across various teams is vital, as the quality of these features directly impacts the accuracy of the ML models. Furthermore, synchronizing features used for offline batch training with those employed for real-time inference can be quite challenging. SageMaker Feature Store addresses this challenge by offering a secure and unified platform designed for feature utilization throughout the entire ML lifecycle. This allows users to store, share, and manage features effectively for both training and inference, fostering the reuse of features across different ML applications. Additionally, it facilitates the ingestion of features from a variety of data sources, including both streaming and batch inputs such as application logs, service logs, clickstreams, and sensor data, ensuring comprehensive coverage of feature collection.
