LimeDS has a configuration entry for specifying the members in a cluster. The configuration can be specified using a .cfg file, which makes it easy to setup the cluster from any installation or deployment process.
Out-of-the-box, LimeDS has no support for discovery & failure detection of nodes in the cluster, but this could easily be added by the user: by integrating with the OSGi Configuration Admin, a REST endpoint could be setup to change the cluster configuration at runtime.
By default, existing LimeDS APIs will replicate the operation over the cluster if the respective operation modifies the state of the framework. No consistency checking is performed.
