[Spread-users] Blocking on membership changes

[Paul Rubel]

Hello,
 
We are currently using spread to communicate between a group of
servers. If a server comes into the group we would like to send the
server some state before it (or other servers) processes any other
"regular" messages. Our vision is to block other messages while we
reconcile the state. Does spread have support for anything like this?
          thank you, 
            Paul
