Blow away the alembic versions table from the database and the folder
with the versions file and patches files on disk and you should be good

What would help more is to focus on the 'kind' of queries you are going

I would recommend just storing them on disk and let the OS VMM deal with
caching for speed. If you are not constrained for space I would
recommend not zlib-ing it either.

Hello list,
sorry for the possibly noob question, I've googled around
if this is OK.
To use compression or not depends on your needs. If the difference in
time consumed is so stark, I would highly recommend compression.

sqlalchemy too.

Take a look at whoosh-alchemy https://pypi.python.org/pypi/WhooshAlchemy

Yes this sounds slightly silly.
Yes I am 100% serious.
I've been working all day on optimizing
as I am concerned they are not aware of any 'business' logic and
only deal with CRUD operations and perhaps complex CRUD if the need arises.
I usually have another abstraction which is generally a factory that
delegates db tasks to the model and deals with all business logicky
stuff, sessions
Exactly what I was looking for! Thanks a ton, I did not realize I could

Thanks again.
