Machine Learning Feature Store with Dynamic Schema Evolution

machine learning feature engineering dynamic schema data lineage
Prompt
Design a machine learning feature store that supports automatic schema evolution, retroactive feature generation, and point-in-time correct feature retrieval. Create a system that can handle feature versioning, support both batch and streaming feature computation, and maintain data lineage. Implement a storage strategy that allows O(1) feature retrieval while supporting complex temporal joins across multiple feature sets.
