JBoss Cache clustering demo

In his session this morning on JBoss Cache, Manik Surtani demonstrated caching and clustering via the lightweight GUI described in “Visualizing JBoss Cache.” It’s a fairly straightforward GUI that gains from it’s simplicity. He mentioned that the GUI demo was available for download, which I found here.

In the demo, Manik is using a buddy node configuration. You can read more about buddy nodes and other clustering configurations via the links in “Full cache at JBoss World“. Regarding one semantic clarification from the talk, a node is a cache instance, that is, a tree node in the data structure. This does not refer to, for example, a physical server node. One audience member who asked about the usage gave the clear language of, “A node is an object that has state in our application and that state needs to be replicated.”
