Is there way to know the cache is fully replicated?

[slartibartphast]

Say I use infinispan on web servers with 1 backup per server.

I want to roll out a new web site, which means nodes will go away and come back. We do this in chunks normally, say 3 servers at once.

If server A's backup is on B, I have to know when I take A offline, that its data is fully replicated elsewhere (say C). Otherwise if I take out A then B too fast, data loss correct?

So is there an API to tell me infinispan has all nodes "stable"? That way my roller could wait for this state before continuing. Or is there something I'm missing here to ensure this?

Hi,

there's a JIRA for this: https://issues.jboss.org/browse/ISPN-2394 The DataRehashedEvent should work.
