Description

See https://github.com/apache/arrow/blob/bae33d622421e6377ab3e9c81dd054c796ab48a3/java/vector/src/main/codegen/templates/MapWriters.java#L174 as discussed on the mailing list

The choice to treat field names as case insensitive is application-dependent, so this logic should probably be pushed downstream into Apache Drill. In the C++ library (and Python wrapper), we are handling std::string names as is without modification.
