如何设置我的Flask应用程序的初始化以将Flask-sqlAlchemy设置为自动提交模式,除非我显式地调用session.begin(),否则不使用事务？

到Instagram年,
autocommit mode; in this mode,Psycopg2 won’t issue BEGIN/COMMIT for
any queries; instead,every query runs in its own single-statement
transaction. This is particularly useful for read-only queries where
transaction semantics aren’t needed. It’s as easy as doing:connection.autocommit = True
This lowered chatter between our application servers and DBs
significantly,and lowered system cpu as well on the database Boxes
