This class is used by
return a pooled connection instance. It is also the class used for
connections obtained with calls to the
connect() method that name a connection pool
(see Section 9.1, “Connector/Python Connection Pooling”).
PooledMySQLConnection pooled connection objects
are similar to
connection objects, with these differences:
To release a pooled connection obtained from a connection
pool, invoke its
close() method, just as
for any unpooled connection. However, for a pooled connection,
close() does not actually close the
connection but returns it to the pool and makes it available
for subsequent connection requests.
A pooled connection cannot be reconfigured using its
config() method. Connection changes must be
done through the pool object itself, as described shortly.
A pooled connection has a
property that returns the pool name.
