   Hi @guocanwen we prefer to handle questions on the [user@ or dev@](https://arrow.apache.org/community/).    The code is a little bit hard to read but does not seem unreasonable.  I would suggest removing the auto values so it is a little bit cleare (and it looks like github my have removed some '>' values.  It would also be useful to understand the source of these values.  For instance it looks like all of you casts are blind casts, it would be good to assert the expected types.
   
   going to resolve, please feel free to start a mailing list discussion (and provide the details above).
