Oh by the way, I'm using SQLite as backend.

I have three different DBs, one is person.db, another is
journal.db, yet another is tag.db. In the documentation it reads:
Vertical partitioning places different kinds of objects,
or different tables, across multiple databases:
engine1 = create_engine('postgresql://db1')
engine2 = create_engine('postgresql://db2')
Session = sessionmaker(twophase=True)
# bind User operations to engine 1, Account operations to
engine 2
Session.configure(binds={User:engine1, Account:engine2})
session = Session()
I noticed that this example only deals with two DBs, and the
parameter is called "twophase". I was wondering if there is any
significance of "two" here? How can I fit my third DB in? Thanks.
"twophase" refers to enabling two-phase commit on supporting backends,
which does not include SQLite. See
https://en.wikipedia.org/wiki/Two-phase_commit_protocol.
