How does the Naming Service maintain persistence? How does this compare with the old Naming Service?
The previous version of the Naming Service (ie VBJ 3.x), kept the NameSpace (the set of contexts and bindings managed by it) in memory. However, it logged every modifiable operation in the NameSpace into a flat logging file. This was used when starting up the Naming Service to recreate the NameSpace. That is how the old Naming Service maintained persistence. The new Naming Service keeps the NameSpace in a user defined backing store. Whether the NameSpace is persistent or not depends on whether the backing store is a persistent storage or not. In the new version, both persistent and non-persistent backing stores are supported.
