PersistentID (Tanzu GemFire 10.0.7)

All Superinterfaces:

DataSerializable, Serializable
```
public interface PersistentID
extends DataSerializable
```
A pattern describing a single member's a set of persistent files for a region. When a member has a region defined with the a data policy of DataPolicy.PERSISTENT_REPLICATE, that members persistent files are assigned a unique ID. After a failure of all members, during recovery, the persistent members will wait for all persistent copies of the region to be recovered before completing region initialization. This pattern describes what unique ids the currently recovering persistent members are waiting for. See AdminDistributedSystem.getMissingPersistentMembers()
