Feature Stores are data warehouse for machine learning and they have become a pivotal technology for managing the entire lifecycle of features, from training different models to providing low-latency access to features by online-applications for model inference. Featurestore.org is an voluntary educational program concerned with disseminating information about Feature Stores for machine learning (ML). It provides a forum for the international community of users and developers of Feature Store platforms and tools to share ideas and learn from each other. Featurestore.org promotes discussion of best practices, new approaches, and emerging technologies for feature engineering, feature management, and feature usage for model training and model serving.
