Answer: _delta_log
Every Delta table is associated with a specific directory named '_delta_log' that houses the transaction log for the table. Whenever records are added, updated, or deleted from the table, a new JSON file is created within the '_delta_log' directory. This mechanism ensures data integrity and supports time travel features.
