What is a Delta Lake?

Delta Lake serves as an open-source storage layer that enhances big data workloads by introducing ACID transactions. This capability allows for reliable data management, ensuring that multiple writers can operate concurrently without issues and that all changes maintain data integrity. The ACID transaction model provides guarantees such as atomicity, consistency, isolation, and durability, which are crucial for maintaining the accuracy and reliability of data across distributed environments.

Additionally, Delta Lake supports features like versioning of data, schema enforcement, and the ability to efficiently handle both batch and streaming data. This makes it particularly valuable in scenarios where data quality, auditability, and performance are critical requirements.

The other options do not capture the full functionality of Delta Lake. While it integrates with cloud storage solutions, it is not merely a cloud storage option; it significantly enhances the data handling capabilities of such storage systems. It is also not classified as a type of traditional database management system or a visualization tool for data analysis, as its core purpose lies in data storage and management rather than data representation or analysis.
