Time travel: What did they do to my data?

In a blog post by Russell Christopher, the integration of Starburst, Iceberg, and Tableau is explored as a means to resolve data anomalies and enhance data analysis through a concept referred to as "time travel." The post details an instance where unexpected changes in data on a familiar dashboard prompted a deeper investigation using these tools. By leveraging Iceberg's capability to view historical data states and utilizing custom SQL in Tableau, the author was able to identify and correct the anomaly, tracing it back to a specific change made in the data. The process involved using Iceberg's time travel feature to navigate through historical snapshots of the data and the rollback procedure to restore the data to its original state. This approach serves as a troubleshooting method rather than a primary querying mechanism due to potential performance trade-offs. The article also introduces the public preview of Warp Speed in Starburst Galaxy and encourages readers to experiment with creating their own Iceberg data lakes using Starburst's platforms.
