Data Warehouse vs Data Lake vs Data Lakehouse: What’s the difference?

Modern data technologies have evolved to accommodate the increasing demand for real-time data processing and storage, leading to the development of data warehouses, data lakes, and data lakehouses. Data warehouses are designed for structured data and historical analysis, whereas data lakes offer flexibility by storing both structured and unstructured data in their raw form. The hybrid data lakehouse combines the best features of both, providing scalable storage with metadata layers for efficient querying and analytics. Real-time streaming data has become crucial, with technologies like Apache Kafka and Apache Flink enabling instant data processing and analysis. However, challenges such as data recomputation and storage costs persist, particularly when dealing with streaming data's volume and velocity. Stream processing solutions, like DeltaStream, address these challenges by offering managed services that simplify the complexity of developing and maintaining stream processing applications, thereby reducing computational costs and latencies in data operations.
