Databricks Runtime 7.2 brings many additional features and improvements over Databricks Runtime 7.1, including:

  • Auto Loader is generally available: Auto Loader is an efficient method for incrementally ingesting a large number of files into Delta Lake. It is now GA and adds the following features:
