Method Details

getJoinValidator

default BiConsumer<DiscoveryNode,ClusterState> getJoinValidator()

Returns a consumer that validate the initial join cluster state. The validator, unless null is called exactly once per join attempt but might be called multiple times during the lifetime of a node. Validators are expected to throw a IllegalStateException if the node and the cluster-state are incompatible.

getElectionStrategies

default Map<String,ElectionStrategy> getElectionStrategies()

Allows plugging in election strategies (see ElectionStrategy) that define a customized notion of an election quorum.

getPersistedStateFactory

default Optional<ClusterCoordinationPlugin.PersistedStateFactory> getPersistedStateFactory()

getPersistedClusterStateServiceFactory

default Optional<ClusterCoordinationPlugin.PersistedClusterStateServiceFactory> getPersistedClusterStateServiceFactory()

getReconfiguratorFactory

default Optional<ClusterCoordinationPlugin.ReconfiguratorFactory> getReconfiguratorFactory()

getPreVoteCollectorFactory

default Optional<PreVoteCollector.Factory> getPreVoteCollectorFactory()

getLeaderHeartbeatService

default Optional<LeaderHeartbeatService> getLeaderHeartbeatService(Settings settings)
