All Implemented Interfaces:

RecoveryStrategy

public class KeepInitialInPartition
extends KeepMinimalInPartition

If the current number of replicas drops below the initial redundancy specified for this replica, and the number of available hosts in this partition is greater than the initial redundancy then create new replicas to compensate for the lost redundancy.
