Hi Steve, You are correct. ADBC is built to leverage Arrow's standards like Flight, so this implementation is the required first step. It is specifically intended to simplify the path to deeper integration with tools like ConnectorX and client libraries such as Polars and Pandas.
Actually, in `ai-code/flight-sql` branch, there are already examples about ADBC in Java[1] and Python[2].
