Yet another newbie question..

Let's say I have an user table in declarative mode:

class User(Base):
    __tablename__ = 'user'
    id = Column(u'id', Integer(), primary_key=True)
    name = Column(u'name', String(50))

When I have a list of users identifiers, I fetch them from db with:

user_ids = [1, 2, 3, 4, 5]
users = Session.query(User).filter(User.id.in_(user_ids)).all()

I dislike using in_ because I think I learned it has bad performance on indexed fields (is that true/false?).

Anyway, is there a better way doing that query?

Thanks!
