Feast
Feast projectFeast is a feature store that keeps one definition of a feature and serves it from two places: an offline store for building training sets with point-in-time correctness, and an online store for low-latency retrieval at inference. Materialization moves values between them, and a registry holds the definitions. Python, Java and Go components ship from the repository.
