I'm curious if this is right working.
In case of using MySQL, both connecting and closing are done per one request.
1st request: connect, close
2nd request: connect, close
3rd request: connect, close
4th request: connect, close
5th request: connect, close
every requests bring both connect and close
This is how I manage MySQL connection and think many of other developer do like this.
BUT..
In case of using mongodb with PyMongo module, it works not like above.
1st request: connect
2nd request: connect
3rd request: (use connection of 1st or 2nd) <= Do not connect but use previous connection
4th request: (use connection of 1st or 2nd) <= same
5th request: (use connection of 1st or 2nd) <= same
Does this keep the connection in app.config and use on after request?
I feel How it works is very difficult from managing connection of MySQL.
Is this normal working?
Doesn't it need to close the connection after using?
