A "refresh", i.e. clearing of caches can be performed by (API may change):
readOnlyGraphDb.getConfig().getGraphDbModule().getNodeManager().clearCache(); and you could maybe keep the default cache_type setting. That should do what you're asking for. 2011/4/5 David Montag <david.mon...@neotechnology.com> > Alfredas, > > A solution based on EmbeddedReadOnlyGraphDatabase would not be able to > benefit from caching, as each "refresh" of the view would have to clear the > caches.
