I have the same reaction as @RussellSpitzer. I like the visualization of snapshots, but I don't consider rollback to be time travel. Rollback alters the state of the table, while time travel actually reads older versions. The trouble here is that there isn't a good SQL demonstration of time travel yet. We've added table names for time travel in 3.2, but we're waiting for Spark 3.3 to get the `AS OF TIMESTAMP` and `AS OF VERSION` syntax. Maybe we should use those anyway? Or maybe we should use Spark's dataframe syntax to demo time travel right now. -- This is an automated message from the Apache Git Service.
