I am actually working on the data engineering side to stream stock data into a data warehouse using python. You should check out this PythonAPI for Robinhood:
I’ve REST enabled my data warehouse to simply execute POST statements which pushes the stock data. Depending on the database you decide to use, you can also just directly execute SQL in Python or batch process tables to the database.
Happy to collaborate if you are interested to work on this more in the future.
