Bulk loading nodes

I have a Jackrabbit workspace with thousands of nodes.  Most of the nodes are in a tree hierarchy, of up to 7 levels.

I need to traverse the entire hierarchy which seems an extremely slow operation.

It seems each Jackrabbit makes a trip to the database for each node.

Is there a way to force Jackrabbit to bulk/eager load child nodes?

Are you using any jcr remoting? Or do you have a remote database behind your persistence manager?

Nodes are usually fetched individually, but Jackrabbit caches them in memory. Using a local database, such as with the derby or h2 persistence managers, will be better. There is no benefit in using a remote relational database for Jackrabbit except for clustering.

Cheers,
Alex
