JSON and XML Autoschema

This video shows the new JSON and XML connectors which are able to read such documents either from a rest API or a file.

The interface will automatically detect the structure of the files and offer you a set of tables. For this to work in XML files you need to have examples of one to many relations in the first file (like an order having several order lines) as this information is not existing in the file itself. In JSON files the array indactes the point where a new table is created.

To debug such connections you can connect to the core container and start pglog.
