Quick Start
pip install feastDetailed Introduction
Feast is an open-source feature store designed to simplify the lifecycle of machine learning features. It enables ML platform teams to manage, serve, and discover features consistently across training and inference environments. By providing an abstraction layer over various data infrastructures, Feast helps prevent data leakage, ensures point-in-time correctness, and decouples ML models from underlying data systems, thereby accelerating the deployment and scalability of AI/ML applications.
