maxWait is is maximum time the connection pool will wait for a connection
to become available so it only has an effect when all maxActive
connections are being used at the same time. maxIdle is the maximum number
of connections what the pool will keep open. Using your settings as an
example, say you reach a point where all 10 connections have beed created
and are in use and that sometime later the nunber of requests drops so
that they can serviced by just a few connections. In this case excess idle
connections will be closed but there will always be at least maxIdle
connections left open.
