> I think there is a bug in the ORC reader : when we specify the fields indexes
> that we want to keep, it does not work correctly. Looking at the code, it
> seems to be because we do "includeTypes" in lieue of "include" when setting
> the ORC options.
> It can be problematic when we want to import an ORC table containing Union
> types as it will do an error at the import, even if we try not to import
> these specific fields.
> The definitions of the corresponding ORC methods are here :
