Another question related to making oslo.db a pypi library and relevant to how taskflow is used.

Currently taskflow has a persistence layer, its using a copy of oslo-incubator db module to do this.

That copied code (soon to be library I hope) has the following:

db_opts = [
    cfg.StrOpt('backend',
               default='sqlalchemy',
               deprecated_name='db_backend',
               deprecated_group='DEFAULT',
               help='The backend to use for db'),
    cfg.BoolOpt('use_tpool',
                default=False,
                deprecated_name='dbapi_use_tpool',
                deprecated_group='DEFAULT',
                help='Enable the experimental use of thread pooling for '
                     'all DB API calls')
]

Now if oslo.db is a library, and taskflow and the integrated project want to use a database backend (potentially a different one) how would that be possible with a single library configuration?

It would seem like the configuration done like this would not allow for that, and I could see taskflow having local sqlite as its backend (different DB config in this case, same backend), while the integrated project using mysql (for whatever its storing).

Would something like that be possible?

Thoughts??
