What kind of transactions does Delta Lake support?

Delta Lake supports ACID transactions, which stands for Atomicity, Consistency, Isolation, and Durability. This capability ensures that all transactions on the Delta Lake table adhere to these four properties, making data management robust and reliable. With ACID transactions, operations like inserts, updates, and deletes are processed in a way that ensures data integrity, even in the face of concurrent writes and reads.

The support for ACID transactions is particularly important for environments where data consistency is critical, as it allows developers to confidently execute complex data operations while knowing that these will either complete successfully or leave the dataset unchanged. This feature helps prevent issues such as dirty reads, non-repeatable reads, and lost updates, making Delta Lake an excellent choice for applications requiring precise data handling and accuracy.

The other options do not accurately represent Delta Lake's capabilities. Non-ACID transactions do not provide the same level of reliability and consistency. Distributed transactions can lead to complications and are not specifically how Delta Lake operates, which relies on its single-table transaction model. Lastly, while Delta Lake can handle batch transactions, it also supports streaming transactions, making it versatile for a variety of workload types.
