Hi, I just started working on adding support for prepared statements and metadata querying in the C++ Drill client. Hopefully, nobody else has started working on this (The Drill jiras don't mention any activity on this), but if it is not the case, let me know.
My working branch is https://github.com/laurentgo/drill/tree/laurent/improve-native-client. For now, I just have a basic interface API ( https://github.com/laurentgo/drill/commit/1f55a3e631cd97016b113b9d4bca07b5e016a25e), and it would be nice if people knowledgeable about the C++ client could review it and give me some feedback. I'm also adding an actual initial implementation in the coming days. Cheers, Laurent
