It seems that the issue you're experiencing with Autoloader not detecting changes in XML files might be related to how Autoloader handles schema inference and evolution.
Autoloader can automatically detect the schema of loaded XML data, allowing you to initialize tables without explicitly declaring the data schema and evolve the table schema as new columns are introduced. However, when Autoloader detects a new column, the stream stops with an UnknownFieldException. This behavior is designed to prevent data loss due to schema changes that Autoloader might not handle correctly.
In your case, when you update the value in XML or delete/remove a column or property in XML, Autoloader might not be able to detect these changes because it's not designed to handle schema changes beyond the addition of new columns.
As a workaround, you could manually set the schema in the Autoloader.
