Hi Gábor,
the code generation in the Table API is in a very early stage and
contains not much optimization logic so far. Currently we extend the
functionality to support the most important SQL operations. It will need
some time until we can further optimize the generated code (e.g. for

Hi Vasia,
regarding your TypeExtractor problem. The TypeExtractor works correctly.
The with() function of the JoinOperator calls the wrong TypeExtractor
method that does not allow missing type info. This is a bug. Can open an

Hi Chengxiang,
I totally agree that the Table API should fully support NULL values. The

SQL as possible. Rows need to be nullable in the near future.

They are currently generic types and handled by Kryo, which has (AFAIK)

Hey Nam-Luc,
I think your problem lies in the following line:

If you do not specify the fields of the class in the String by using

I have looked into your issue. You can simply use
env.createInput(InputFormat,TypeInformation) instead of env.readFile()
then you can pass TypeInformation manually without implementing
ResultTypeQueryable.
