I try to stay away from Events in production. I now need to catch modifications of a particular column in order to expire some data cached onto the object.
Is there a measurable overhead for catching a single column? e.g. @event.listens_for(ObjectClass.column, 'set') The alternative is to use a setter function - which I am fine with. This is in an app that needs to be a bit more performance oriented, so I figured I would ask before doing a benchmark. -- 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.
