Beyond Medallion: Next-Generation Lakehouse Architectures for Real-Time AI-Driven Enterprise Decision Systems
A comprehensive analysis explores the evolution of lakehouse architectures and their applicability for real-time AI-driven decision systems. State-of-the-art architectures for data ingestion and streaming processing, as well as a hybrid extension of the medallion framework, form the foundation for semantics-aware online feature engineering, high-availability model serving, and comprehensive drift monitoring and detection. Provenance tracking and preservation, consistency model selection and conflict handling, access and sharing control, privacy and compliance requirements, and benchmark construction for end-to-end performance evaluation are discussed. Case studies demonstrate how next-generation enterprise real-time decision systems satisfy at least all of data quality, freshness, and access control. Real-time AI capabilities are increasingly being adopted in enterprise systems for a variety of purposes, including customer experience enhancement, risk mitigation, fraud detection, and service optimization. AI solutions in these domains dynamically adapt using data generated in real time, relying on various online and near-real-time algorithms that systematically consume and produce data and decisions. Such solutions find their origins not only in classic fraud detection, recommender engines, and online bidding systems, but also in AI domains such as learning-to-rank, multi-armed bandits, reinforcement learning, transfer learning, deep reinforcement learning, online learning, and continual learning. Real-time feature engineering pipelines in these sectors address a wide range of challenges, such as content-based spam detection, sentiment analysis, stock market prediction, and stock price analysis.
