Explanation:
The Delta Lake transaction log (also known as the Delta Log) is an ordered record of every commit made to the table. This log is essential for time travel because it allows Delta Lake to reconstruct the exact state of a table at any point in history or at a specific version by tracking which data files were added or removed during each transaction.
