Delta Lake 4.0 and Delta Kernel: What's New in the Future of Data Lakehouses

In data storage, the idea of a data lakehouse has transformed data storage and analysis in organizations. Data lakehouses combine the low-cost and scalability storage ability of data lakes and data warehouse’s reliability and performance. In this space, some players have emerged, such as Delta Lake, as strong open-source frameworks for implementing robust ACID-compliant data Lakes. Now, with the introduction of Delta Lake 4.0 and the development of Delta Kernel, the future of the lakehouse architecture is in a revolutionary transition. Brimming with features driving performance, scaling, and interoperability, these updates are to keep up with the increasing dynamics of data workloads in 2025 and beyond.
