Type Members

1.  final class AutoDowning extends DowningProvider

   Used when no custom provider is configured and 'auto-down-unreachable-after' is enabled.

2.  class Cluster extends Extension

   This module is responsible cluster membership information.

   This module is responsible cluster membership information. Changes to the cluster information is retrieved through #subscribe. Commands to operate the cluster is available through methods in this class, such as #join, #down and #leave.

   Each cluster Member is identified by its akka.actor.Address, and the cluster address of this actor system is #selfAddress. A member also has a status; initially MemberStatus Joining followed by MemberStatus Up.

3.  trait ClusterMessage extends Serializable

   Base trait for all cluster messages.

   Base trait for all cluster messages. All ClusterMessage's are serializable.

4.  trait ClusterNodeMBean extends AnyRef

   Interface for the cluster JMX MBean.

5.  abstract class ClusterScope extends Scope

6.  final class ClusterSettings extends AnyRef
7.  sealed trait ConfigValidation extends AnyRef

   @DoNotInherit()

8.  abstract class DowningProvider extends AnyRef

   API for plugins that will handle downing of cluster nodes.

   API for plugins that will handle downing of cluster nodes. Concrete plugins must subclass and have a public one argument constructor accepting an akka.actor.ActorSystem.

9.  final case class Invalid(errorMessages: Seq[String]) extends ConfigValidation with Product with Serializable
10.  final class JoinConfigCompatCheckCluster extends JoinConfigCompatChecker

11.  abstract class JoinConfigCompatChecker extends AnyRef
12.  class Member extends Serializable

    Represents the address, current status, and roles of a cluster member node.

    Represents the address, current status, and roles of a cluster member node.

    Note: hashCode and equals are solely based on the underlying Address, not its MemberStatus and roles.

13.  sealed abstract class MemberStatus extends AnyRef

    Defines the current status of a cluster member node

    Defines the current status of a cluster member node

    Can be one of: Joining, WeaklyUp, Up, Leaving, Exiting and Down and Removed.

14.  final class NoDowning extends DowningProvider

    Default downing provider used when no provider is configured and 'auto-down-unreachable-after' is not enabled.

15.  final case class UniqueAddress(address: Address, longUid: Long) extends Ordered[UniqueAddress] with Product with Serializable

    Member identifier consisting of address and random uid.

    Member identifier consisting of address and random uid. The uid is needed to be able to distinguish different incarnations of a member with same hostname and port.
