Machine Learning (ML) pipelines are the fundamental building block for productionizing ML models. However, much introductory material for machine learning and deep learning emphasizes ad-hoc feature engineering and training pipelines to experiment with ML models. Such pipelines have a tendency to become complex over time and do not allow features to be easily re-used across different pipelines. Duplicating features can even lead to correctness problems when features have different implementations for training and serving. In this demo, we introduce the Feature Store as a new data layer in horizontally scalable machine learning pipelines.
