Cross-Site Replication: State Transfer between sites ---------------------------------------------------- Key: ISPN-2342 URL: https://issues.jboss.org/browse/ISPN-2342 Project: Infinispan Issue Type: Feature Request Components: Cross-Site Replication Affects Versions: 6.0.1.Final Reporter: Erik Salter Assignee: Pedro Ruivo Labels: roadmap Fix For: 7.0.0.Beta1, 7.0.0.Final 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
