Which capability does not belong to the Delta Lake format?

Delta Lake is designed to enhance the management of big data and provide data reliability on data lakes. One of its core capabilities is to handle large-scale data processing with features that mimic traditional relational databases while maintaining the benefits of distributed architectures.

The key capabilities of Delta Lake include:

• Relational-like features: Delta Lake supports ACID transactions, schema enforcement, and governance, which help manage data consistency and integrity similar to relational databases.

• Caching mechanisms: It employs caching mechanisms to speed up data access and improve performance when querying large datasets, making data retrieval faster and more efficient.

• SQL-on-files commands: Delta Lake provides capabilities to run SQL queries directly on files, leveraging SQL syntax to interact with the data, which facilitates data manipulation and analysis.

The choice of file sharing over email is not a capability that pertains to Delta Lake. Delta Lake focuses on operations related to data storage, management, and querying, rather than communication or file transmission methods that are external to the data processing environment.
