Hi All,
In the latest jdbc driver,multi backends can be assigned in the URL as following.

aconnection is successfully established.
But there is a performance problem .if the first host is down,
all connecting must be blocked until connect timeout at first,
and then try connect to the next host.
Why not adjust the order of hosts dynamically?
For excample, after a successful connecting,if the target host is not the first host,
swap the target host and the first host.
And then subsequent connecting will try the most suitable host at first.
