Not yet. If you'd like to see this feature, please file a JIRA issue.

I'm afraid so, yes. File-based persistence managers do not provide
transaction isolation, e.g. one cluster node could potentially
overwrite elements in the file system before the whole operation is
actually committed.

This algorithm assigns a random cluster id to a cluster node: I'd
rather use a well-defined, sensible cluster id, which also helps when
tracking down what cluster node was responsible for a change.

No, again you'll need a db persistence manager.

Kind regards
