This will help you achieve maximum concurrency in the cache. "srnm" wrote : | Do the jdbc loaders update a row/single key in a node at a time? If so, how do they support the semantics of the cache? | By using a separate shared lock on the Fqn.

Is it in concurrency, replication or cache loading? :-) Either way though, use the tree structure fully, don't put too much in each node.
