How can you use Delta Lake's time travel feature to audit changes to a dataset over the last month for regulatory compliance?
A
Configure automated alerts in Azure Monitor to track and report changes in real-time, negating the need for time travel.
B
Write a Spark SQL query leveraging the DESCRIBE HISTORY Delta Lake command to list all changes, filtering by the timestamp for the last month.
C
Use the Databricks CLI to export data at the current version and manually compare it against a version from one month ago.
D
Implement a Databricks notebook that uses the VERSION AS OF syntax to snapshot the dataset at weekly intervals, comparing consecutive snapshots for changes.
