makes sense, the connection is pooled. if you make lots of connections, like
more than five simultaneous connections, you'd see more of it, if you call
engine.dispose() then engine.connect(), you would see it again also, etc.
Also try using NullPool, then you'd see the hook run every time
Yes but only once when the app starts up.

Ok that makes sense and clarifies some stuff for me. I have tried your
implementation but it doesn't seem like its getting new connections. We are
using sessionmaker(). So basically this is what we are doing. Can you help
me understand if we are doing this right and if any changes need to
no, create_engine() does not connect at all. connections occur when you
first call `engine.connect()`. From that point, the behavior of subsequent
`engine.connect()` calls depends on connection pool configuration. all
connection pools have points at which they continue to establish new
That makes sense but doesn't connect only happen once when create_engine()
is called?
