A data lake is a centralized storage for diverse raw data. Delta Lake enhances this concept, evolving it into a Lakehouse architecture. Compatible with various compute engines and programming languages, Delta Lake ensures data integrity through ACID transactions and handles massive datasets seamlessly. As an open-source framework, it follows community-driven standards, unifying batch and streaming processing with exactly-once semantics.
Delta Lake prevents data corruption with schema evolution/enforcement, maintains an audit trail, and offers versatile APIs for data manipulation. In essence, Delta Lake transforms a traditional data lake into a scalable, open, and feature-rich Lakehouse solution for comprehensive data management and analytics.
