What feature of Delta tables helps ensure data consistency?

The feature of Delta tables that plays a crucial role in ensuring data consistency is the ACID transaction capabilities. ACID stands for Atomicity, Consistency, Isolation, and Durability, which are fundamental properties that guarantee reliable processing of database transactions.

With Delta tables, the concept of Atomicity ensures that all operations within a transaction are completed successfully, or none at all. Consistency implies that any transaction will bring the database from one valid state to another, preserving data integrity. Isolation guarantees that concurrent transactions do not interfere with each other, maintaining the correctness of data. Durability assures that once a transaction has been committed, it will remain so even in the face of system failures.

This combination of properties fundamentally supports the integrity and consistency of the data stored in Delta tables, making it a robust solution for managing large-scale data sets in environments where consistency is critical.

The other features listed do not enhance the consistency of data to the extent provided by ACID transactions. Static data storage, for instance, relates to the immutability of data rather than its transactional integrity. Manual control over file versions might offer some level of oversight but does not inherently guarantee consistency as transactions are processed. The introduction of non-relational storage does not pertain to the management of
