Explain how Delta Lake's transaction log ensures ACID compliance. Discuss a specific use case where the transaction log's role in maintaining data integrity is critical.
A
Delta Lake's transaction log records all changes to the data, ensuring atomicity, consistency, isolation, and durability, critical in scenarios like real-time analytics where concurrent reads and writes must maintain data integrity.
B
The transaction log in Delta Lake is only used for logging purposes and does not contribute to ACID compliance.
C
Delta Lake does not use a transaction log, leading to potential data inconsistencies in concurrent operations.
D
The transaction log ensures ACID compliance by periodically flushing data to disk, irrelevant to concurrent operations.
