Hi,
sorry for the late reply. I've now made some measurements, and
repeated those two a couple times to avoid caching effects. I've
reduced it to the innermost sql statement. Here they are:
SELECT entrypoint_id, ...20 about fields ..., ROW_NUMBER() OVER
(ORDER BY creationdate DESC, entrypoint_id

hit by that bug (or the side effects were not as tremendous as in my

Thanks anyway for looking at this and fixing the problem.

I will be interested to know if using ORM for a large scale data

Has SQLAlchemy been put to test ever for a select query which involves
