             Summary: The x-site implementation needs an inter-site state transfer mechanism
                 Key: ISPN-2342
                 URL: https://issues.jboss.org/browse/ISPN-2342
             Project: Infinispan
          Issue Type: Feature Request
          Components: Cross-Site Replication
    Affects Versions: 5.2.0.Alpha4
            Reporter: Erik Salter
            Assignee: Mircea Markus


To bring up a new site or recover a failed site, I need an inter-site state transfer mechanism for synchronizing keys.

Note that initially, this should a manual process that is invoked on one site to one of its configured backups.

This should be based on the non-blocking state transfer mechanism for consistency.  

The pseudo-design may look similar to the following:

- Manually invokable, background thread
- Since the bridge end is open, there are writes happening to keys.  Keep track of the puts/removes on the main data owner.
- Iterate through the key set.
- If the key has already been modified since the process started, discard.
- Else synchronously write the key value in a TX context
