Re: performance problem of Failover Datasource?

Hi

In this patch,I use Collections.synchronizedSet to synchronize within multi-threads.
But i worry about locking operation is a litter frequent by Collections.synchronizedSet
  and may affect performance.
I think using keword "synchronized" explicitly instead of Collections.synchronizedSet
  may reduce times of locking.Is there any better suggestion?


In addition, I have a idea.
By adjusting the order of hosts we also can implement a simple load balance
while all of the hosts are master or read only slave.
For example:
Basically pick up the server randomly.If one server had dead remove it from the candidates,
and retry the next server.
And after a while(can be configured) re-add the dead host to the candidates because the dead
server may had been repaired.


What about that?
