Great - I've implemented mentioned pattern and it works!

Thank you!

Yes, the approach would be to use the exact same session:

     dbSession = SQLSession.sql_session()
     functionA()
     functionB()
dbSession.close()

It looks like functionA and functionB each call `SQLSession.sql_session()`, which will cause problems. I believe that will create multiple sessions, which will have different data and may cause blocking and transactional issues.

I usually write my celery tasks like this:

     def task_foo():
         dbSession =  new_session()
         functionA(dbSession)
         functionB(dbSession)
dbSession.close()
