> Currently Drill fails on schema changes in JSON. Some of these are due to
> fundamental limitations of the Drill record representation. Others are due to
> Drills lack of full support for mutating schema. This can be solved
> temporarily by reading in all data as strings and allowing users to use some
> combination of case statements and UDFs to appropriately handle their own
> schema mutations.
