Not yet. If you'd like to see this feature, please file a JIRA issue. > - With the clustered configuration we are limited to a db persistence > manager, with the kind of data we ingest into our system we see a huge > increase in the time it takes to process them. I think this is caused by the > db persistence manager - do we REALLY have to use a db persistence manager? 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. > - we found that you don“t need to give a cluster id, it seems there is an > algorithm to provide individual servers with cluster ids - is this safe to > use? 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. > - versioning is still configured for the local file system, is this ok for a > clustered installation? No, again you'll need a db persistence manager. Kind regards Dominique
