Hi, I've been working on porting the cookie middleware from Java to C++/Python clients in this PR: https://github.com/apache/arrow/pull/8655
I'm looking at the Python impl now. The Python Flight API for middlewares seems oriented towards writing middlewares directly in Python, which would get wrapped in a C++ middleware for running Python code. It seems to me like there are two solutions for this: 1. Creating some helper static function in Python which takes a C++ middleware pointer and wraps it in a Python middleware, which in turn would get wrapped in a C++ middleware again in the C++ layer. 2. Expose the concept of letting the Python client accept 'pass-through' middleware objects that don't implement the Python interface, and are interpreted by the C++ layer to be direct C++ middleware objects. The former seems like a better of abstraction and seems like the way to go, although less efficient. The latter is obviously less convoluted, but brings up issues if we ever change the Python implementation from being a wrapper around C++. -- *James Duong* Lead Software Developer Bit Quill Technologies Inc.
