Auto-tuning capability available for external tables?

[Amit_Dass_Chmp]

If I am using Databricks Runtime 11.3 and above to create managed Delta tables cataloged in Unity Catalog (Databricks’ data catalog), I don’t need to worry about optimizing the underlying file sizes or configuring a target file size for my Delta tables because Databricks will carry out this task automatically in the background as part of the auto-tuning capability.

Does Auto-tuning capability available for external tables as well?

Hi @Amit_Dass_Chmp ,

Yep, according to documentation. As of second question, such capability will be available in the future.
