What is Feast?
Feast is an open-source feature store for defining, managing, validating, and serving features for production ML systems. It consists of an offline store that pulls historical features for model training and a low-latency online store for real-time serving. It reuses existing infrastructure and provides a Python SDK, an optional feature server, a UI, and a CLI. Point-in-time correct feature sets prevent data leakage.
