Enum Class RecoveryStrategy

java.lang.Object

java.lang.Enum<RecoveryStrategy>

io.github.bucket4j.distributed.proxy.RecoveryStrategy

All Implemented Interfaces:

Serializable, Comparable<RecoveryStrategy>, Constable

public enum RecoveryStrategy
extends Enum<RecoveryStrategy>

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 DefaultBucketProxy detects that bucket state is missed, it applies this strategy to react.
