OTOH Pandas/Numpy are great for results. One pattern that I'm hoping to try is running heavy lifting in SQL, transfer results via Apache Arrow, and manipulate the result set in Python with aforesaid libraries. I don't know enough about how Arrow handles streaming to understand how this would really work but it would break away from the single-threaded connectivity with expensive ser/deser databases have used since the days of Sybase Db-Library, the predecessor to ODBC. 36 years is probably long enough for that model.
