I am using SQLAlchemy version 0.9.7. I have ~ 400 tables that I
automatically reflect from the database. I would like to cPickle the
metadata after reflection and store this, then subsequently unpickle the
metadata and use it (for speedup) rather than use reflection again.

Hi,
I am working on a web site using Python Django and SQLAlchemy ORM. I want
to do all read operations in separate database and write operations in
separate database.
So I tried *Mike Bayer*'s solution (

Just to add to Michael's reply -- keep in mind that how you handle the
session (commit/rollback/close) will impact the state of any objects the
session loaded if you're using the ORM and that can have implications in
your app.
The default behavior of sessions is to have `expire_on_commit=True`
