8.3. State Transfer

State Transfer refers to the process by which a JBoss Cache instance prepares itself to begin providing a service by acquiring the current state from another cache instance and integrating that state into its own state.

8.3.1. State Transfer Types

There are three divisions of state transfer types depending on a point of view related to state transfer. First, in the context of particular state transfer implementation, the underlying plumbing, there are two starkly different state transfer types: byte array and streaming based state transfer. Second, state transfer can be full or partial state transfer depending on a subtree being transferred. Entire cache tree transfer represents full transfer while transfer of a particular subtree represents partial state transfer. And finally state transfer can be "in-memory" and "persistent" transfer depending on a particular use of cache.
