You could also use sqlacodegen (https://pypi.python.org/pypi/sqlacodegen/) to only reflect once -- generating the python models for you. Then you could split the python models into a series of files that you import as needed to cut-down on in-memory size. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
