Subject Re: JavaTypeFactoryImpl Record class is reused
Date Tue, 12 Jan 2016 06:07:59 GMT
The behavior you are seeing might be intentional. Note that the argument to JavaTypeFactoryImpl.register
is SyntheticRecordType. The intent is to create a record type — internally, a java pojo
class — that has the desired fields to carry around records in generated code.

Usually I think I use RelDataTypeFactoryImpl rather than JavaTypeFactoryImpl, and I think
that does the right thing — checks field names and types before declaring that two types
are equivalent. Not sure why you are ending up with a JavaTypeFactoryImpl.
