postgresql – 在Flask-SQLAlchemy中自动提交

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？

会议“begins a database transaction as soon as it starts communicating”.这对Po​​stgres的影响比MysqL更难吗？

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

我想你可以在Flask-sqlAlchemy中设置autocommit这样做：

from flask.ext.sqlalchemy import sqlAlchemy
db = sqlAlchemy(session_options={'autocommit': True})
