I would like to return a list of all invoices that are assigned to a
specific client. However the relationships are built so that an

Hi,
I use Beaker in production to help speed up the delivery of game

large queries that don't change.
We don't use it at the query level but as a way to cache whole results
from sqlalchemy.
