Subject Re: PooledConnectionFactory + Failover Transport combination
Date Fri, 27 Jul 2012 10:15:44 GMT

the pooled connection factory will try to create maxConnections
(default 1) and then reuse them from the pool. The process of
connections creating (failover and randomize) is not related to the
pool at all. With failover in case, the client (and the pool) will not
even see host1 connection problem as transport itself will reconnect
to host2.
