Hi all,
I'm trying to share an object with a thread, I already tryed to use
Session.merge but I'm doing something wrong,
here is a test case:
from sqlalchemy import
= create_engine(connectionstring, echo=settings.DEBUG,
echo_pool=settings.DEBUG,
pool_size=20, max_overflow=400)
s = scoped_session(sessionmaker(bind=engine))
so the session was not scoped and give the errors I report, thanks for

Hi all,
I know sqlalchemy session is not thread safe but in my application I

I have my session defined as following:

pool_size=20,
threads making the same query

After the select there is an insert, can three concurrent threads

Hi,
You should take a look at MapperExtension. Then you'll be able to add
method which would be called depending on the orm actions.
For example, you'll be able to add
objects in memory
and without perform an update?
