>From my point of view, one difference between SingleConnectionFactory and
PooledConnectionFactory is that SingleConnectionFactory reuse the same
connection among all the listeners/consumers and PooledConnectionFactory
shares a pooled of connections among the listeners/consumers.
I think if I use
I'd say using a PooledConnectionFactory is a far more common configuration
in production environments than using SingleConnectionFactory. Allowing
each application to use anywhere from 0 to M (pool size) connections based
on its current load sounds better than having N apps using 1 connection
each
