concurent queries

Peewee recomends to conect() just before request and close() after executing user code.

i.e. from documentation: http://docs.peewee-orm.com/en/latest/peewee/database.html#creating-a-database-connection-and-tables

database = SqliteDatabase('my_app.db')

def before_request_handler():
    database.connect()

def after_request_handler():
    database.close()

On async app handlers are coroitines and requests can be processed while another one waiting bigger data.

Is there way to get another connection from pool and do requsts on it instead of using shared database connection?

Context manager maybe?

On the line 875 we have:

       if self._async_conn:
            return

So connect_async() is called only once to initialize a connection pool. AsyncDatabase class is not the same as in original peewee, it’s just a single instance per application (usually) - wrapper to real async database driver which handles multiple connections under the hood.
