Backwards Compatibility Mode
Set BackwardsCompatibilityMode to true to use the XML/JSON functionality and features available in the 2017 version.
When set to true, the driver will function the same as the 2017 version. When set to false (default), the new flattening features will be available. This includes DataModel, FlattenArrays, FlattenObjects, as well as the dynamic flattening of tables and columns via a SQL query.
The backwards compatibility mode will continue to be supported/improved.
