longshot, i know. We've got some legacy twisted code that does raw operations via a twisted.enterprise.adbapi connection pool with the psycopg2 driver. Other services in this deployment are configured to use SqlAlchemy for all operations - this is the legacy holdout.
There are a few chunks of blocking code that have a performance bottleneck caused by multiple updates to the same records. I'm wondering if it's possible to leverage the orm on top of this existing connection's cursor. The basic idea would be this: s = Session(connection=twisted_dbapi_cursor) foo = s.query(Foo).get() s.flush() txn.commit() s.close() I've seen stuff about using an engine build off an existing connection, but I only have the cursor - not the connection itself. The connection is a private attribute in the cursor, so i could potentially access it.... but that could cause issues that scare me at this point. -- SQLAlchemy - The Python SQL Toolkit and Object Relational Mapper http://www.sqlalchemy.org/ To post example code, please provide an MCVE: Minimal, Complete, and Verifiable Example.
