Dear Sirs,

I understand it's possible to use databases without DAL.
For example function in controller:

def values():
    client = pymongo.MongoClient('localhost', 27017)
    db = client.mybase
    mytable = db["mytable"]
    res = mytable.find()
    .....

    return dict(....)

And of course it works.
But is it fast to connect/disconnect every time in function? What's about 
connection pool?
I consider connection pool could increase access to database. 

1. Actually I would like to ask how to access to database without DAL but 
at maximum speed?
2. Do I need connection pool for fast database access? (I think, yes.)
3. How could I build custom connection pool for database access without 
DAL? Or any solution to re-use connections to database server? Any examples?
