    -- Can be used to explicitly disable or enable query recording.
       Query recording automatically happens in debug or testing mode.

 -- SQLALCHEMY_TRACK_MODIFICATIONS:
    -- If set to True, Flask-SQLAlchemy will track modifications of
       objects and emit signals.
       The default is None, which enables tracking but issues a warning that
       it will be disabled by default in the future.
       This requires extra memory and should be disabled if not needed.
