The transaction log is used solely for logging metadata changes and does not interact with cloud storage.

Delta Lake uses the transaction log to record every operation on the data, ensuring that each operation is atomic. In case of failure, the log allows Delta Lake to recover the last consistent state from cloud storage.

Delta Lake uses the transaction log only for read operations and relies on cloud storage for write operations.

The transaction log in Delta Lake is used to optimize query performance and does not contribute to atomicity or durability.
