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.
