[Spread-users] replicated state machine with spread

[Dan Mihai Dumitriu]

Hi all,

I am implementing a replicated state machine using Spread (Java API)
and I would like to know how I can do a proper state transfer when a
new replica joins the group.  (New replica joins, it has no state, it
must get a copy of the current state from an existing member, and
then all replicas must process all input messages in the same order.)
Is it possible to guarantee that a certain message (from the group
leader) is delivered first after a view change, before any other
messages?  In my system, I have several senders (which are in fact
not part of the spread group) and two receivers, which implement the
RSM.

Cheers,
Dan
