I have a few basic questions on the "transactional" events as I try to
extend pyramid's logging system to grab them.
1. do the events need to return anything, or can they just sit there and be
dumb?
for example:
@event.listens_for(Engine, "commit")
def _commit(conn):
pass
some frameworks have listeners where a return value is required for things
to pass/fail. the sqlalchemy docs didn't note anything, so i want to be
sure they can be dumb.
2. is there a way to time these? a `commit` can trigger many deferred
foreign key checks, which could take a while. i don't see an apparent way
to time this.
i don't need to time anything. the library is full featured though, and
most times i think a function doesn't exist, it does -- but i missed it in
the docs.
i have a feeling that its not possible to time a `commit`, because it would
add a bunch of cruft for a weird use-case that 2 people would use. it
seems worth asking about though.
