Hmm I don't quite understand than when documentation on active/active i=
s trying to say: <br>&gt; All actions other than
          publishes go only to the master, and the master then
          broadcasts the effect of the actions to the slaves<br><br>Does it=
 mean that slaves are acting as proxies to master? Which means that for per=
formance reason it is better for the clients to connect to master if possib=
le?<br>
And why publishes are exception to this rule?<br><br>Vadim.<br><br><br><div=

connectivity. There are a number of solutions that you could use:<br>

o) Change the DNS on failure<br>
o) a plain TCP load balancer like haproxy or a router-based one<br>
o) mobile IP addresses as can be done with something like pacemaker<br>
