> 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.
