Hi,
when a repository cluster is used, it seems that a common problem many
people have is to detect if an observation event is send because of changes
on the local instance or a remote instance of the cluster.
This is especially important if you want to do post processing of data
based on observation (the post processing should only be done by one
instance in the cluster).
A current solution is to cast the jcr event object to the EventImpl of
jackrabbit core which is obviously not a nice solution :)
So what about adding an event interface to jackrabbit api which extends the
jcr event interface and adds the isLocal() method?

Just to be sure (and document it), client code would like this, right?
javax.jcr.Event event = events.nextEvent();
if (event instanceof org.apache.jackrabbit.api.JackrabbitEvent) {
if ( ((org.apache.jackrabbit.api.JackrabbitEvent) event).isLocal() ) {
// event from local cluster node
} else {
// event from remote cluster node
}
} else {
// not a jackrabbit repository
}
Yes, that's exactly the idea.
