```
public final class PersistentManager
extends PersistentManagerBase
```
Implementation of the Manager interface that makes use of a Store to swap active Sessions to disk. It can be configured to achieve several different goals:
- Persist sessions across restarts of the Container
- Fault tolerance, keep sessions backed up on disk to allow recovery in the event of unplanned restarts.
- Limit the number of active sessions kept in memory by swapping less active sessions out to disk.
