Jihoon Son commented on TAJO-1353:
----------------------------------
[~hyunsik], sorry for confusing you.
I just looked over the patch, and would like to review the changes of
SQLAnalyzer more carefully because the patch contains not only the changes
related to the nested record, but also some refactoring codes.
I'll finish my review, soon.
> CREATE TABLE should support the nested record definition.
