class SignallingSession(Session):

Description _{[extrait de SignallingSession.doc]}

The signalling session is the default session that Flask-SQLAlchemy
    uses.  It extends the default session system with bind selection and
    modification tracking.

    If you want to use a different session you can override the
    :meth:`SQLAlchemy.create_session` function.

    .. versionadded:: 2.1
        The `binds` option was added, which allows a session to be joined
        to an external transaction.
