Is there a way to have create_engine NOT create a sqlite database in the
event that one does not exist?
thanks

When the database restarts my services are flooding the database
connection. I wonder if in SQLAlchemy has a parameter that step
create_engine () it does a delay between an attempt and another connection.
I need him to try to connect if you can not it wait X time to make a new
attempt.

I think you need to reword this question. Right now it says, Is there
a way to call a function X() and have it NOT do X? Doesn't make much
sense.

Thanks for your input! It helped my to find a bug in my code.
I inserted 0 for false, 1 and 2 for true.
However, inserting a bad value for boolean using SQLAlchemy should also
result in an exception and not only selecting a boolean with a bad value.
Thanks again,

I've had issues like this in the past, and in the worst situations your
services can end up giving your system a ddos.
what i usually do to avoid this, is implement a delay on the connection
pool itself, and have each service cycle through a set of delays with a
different starting point in
I have some buried-in-the-codebase-since-0.7 upsert code that uses `merge`.
In order to avoid certain attributes from being used in the merge
comparison, the attributes were deleted using delattr..
The code looks something like this:
db_obj = sess.query(obj_type).filter_by(**filters).one()

this error happened.
Traceback (most recent call last):
File server.py, line 112, in module
location = Location(galileo, gateway, processing)
File C:\Desenvolvimento\locations\Location.py, line 41, in __init__

I researched and found another way to do which was:
from retrying import retry
@retry(stop_max_delay=1)
def get_con_gateway(self):
con = self.gateway['engine'].connect()
return con
I used retrying module and made a method to create the connections.
