What advantage does using Delta Lake offer for big data applications?

Using Delta Lake provides ACID compliance for reliability and consistency, which is critical for big data applications. This means that transactions within Delta Lake adhere to the properties of atomicity, consistency, isolation, and durability. This is particularly important in environments where concurrent data modifications may occur, such as in data lakes used for real-time analytics or during batch processing.

With ACID compliance, you can ensure that all operations are completed successfully or none at all, which prevents data corruption and maintains a high level of data integrity. This is a significant advantage over traditional data lakes, which often lack such transactional guarantees and can lead to complications such as data inconsistencies or loss of data when multiple processes attempt to read and write simultaneously.

The incorrect options present points that do not accurately reflect the key benefits of Delta Lake. While storage costs, file format limitations, or increased manual data entry may have relevance in other contexts, they do not highlight the primary strengths of Delta Lake in facilitating reliable big data architecture, which is fundamentally based on its capability to provide ACID transactions.
