* Specifies the reaction which should be applied in case of previously saved state of bucket has been lost.
*
* The state of bucket can be lost by many reasons, for example:
*
* - Split-brain happen.
* - The bucket state was stored on single jvm node without replication strategy and this node was crashed.
* - Wrong cache configuration.
* - Pragmatically errors introduced by vendor.
* - Human mistake.
*
*
* Each time when {@link DefaultBucketProxy} detects that bucket state is missed, it applies this strategy to react.
