Hi, I am writing an application server using twisted and sqlalchemy. On the server - database relation I use a pool of threads each with its own database connection, session etc.
The problem is that I have 2 tables (one with products and one with events that might happen to a product) and I think I might have concurrency problems with them (i.e: when selecting a chunk of 50 products from the first table, I need to know for certain that another thread is not inserting the same event in the second table as I am doing with the already selected chunk from the first table). I am using a transactional, autoflushing session. I was thinking about table locking but, it doesn't seem like a good option. Any advices? Thanks. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
