Which of the following statements about Delta Lake is true?

Delta Lake is designed to bring reliability to data lakes by providing key features such as ACID transactions, which stands for Atomicity, Consistency, Isolation, and Durability. This set of properties ensures that all database transactions are processed reliably, allowing for changes to be made safely without compromising the integrity of the data. This means that users can perform write operations while maintaining the ability for queries to read a consistent view of the data, even during updates.

The significance of this feature lies in its ability to support both batch and streaming data processing, enabling users to have a single source of truth for their data analytics. By implementing ACID transactions, Delta Lake allows data analysts and engineers to manage large-scale data more effectively and to maintain high data quality throughout various operations.

Other options suggest limitations that don't align with the capabilities of Delta Lake. For example, stating it only supports unstructured data overlooks its versatility in handling structured and semi-structured data. Suggesting it only allows for batch processing ignores its real-time streaming capabilities. Therefore, the focus on ACID transactions as a core strength of Delta Lake, ensuring data integrity and reliability, accurately reflects the essential features of this technology.
