Hello- I have a feeling this question will have a painfully simple answer so I apologize in advance:
I am interested in the Gandiva portion of the apache arrow project, as a SQL-like interface to arrow data. I browsed the source code and I see a lot relating to building and evaluating expression trees, but I cannot find anywhere where the Parser/Lexer frontend is defined. I'm also looking for a binary/executable interface where I could evaluate a string expression in the Gandiva language against some arrow data. Am i sorely mistaken about the purpose of this sub-project? Or am I missing something quite obvious? Thank you, and thanks for creating this excellent project.
