Enum ConflictResolutionType

  • All Implemented Interfaces:
    Serializable, Comparable<ConflictResolutionType>

    public enum ConflictResolutionType
    extends Enum<ConflictResolutionType>
    The type of conflict resolution to configure for the bucket.

    A conflict is caused when the source and target copies of an XDCR-replicated document are updated independently of and dissimilarly to one another, each by a local application. The conflict must be resolved, by determining which of the variants should prevail; and then correspondingly saving both documents in identical form. XDCR provides an automated conflict resolution process.

    • Enum Constant Detail


        public static final ConflictResolutionType TIMESTAMP
        Conflict resolution based on a timestamp.

        Timestamp-based conflict resolution (often referred to as Last Write Wins, or LWW) uses the document timestamp (stored in the CAS) to resolve conflicts. The timestamps associated with the most recent updates of source and target documents are compared. The document whose update has the more recent timestamp prevails.


        public static final ConflictResolutionType SEQUENCE_NUMBER
        Conflict resolution based on the "Sequence Number".

        Conflicts can be resolved by referring to documents' sequence numbers. Sequence numbers are maintained per document, and are incremented on every document-update. The sequence numbers of source and target documents are compared; and the document with the higher sequence number prevails.

      • CUSTOM

        public static final ConflictResolutionType CUSTOM
        Custom bucket conflict resolution.

        In Couchbase Server 7.1, this feature is only available in "developer-preview" mode. See the UI XDCR settings for the custom conflict resolution properties.

    • Method Detail

      • values

        public static ConflictResolutionType[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
        for (ConflictResolutionType c : ConflictResolutionType.values())
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static ConflictResolutionType valueOf​(String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        name - the name of the enum constant to be returned.
        the enum constant with the specified name
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null
