Public Methods

Method	Description
ClusterService ( IClusterOperator clusterOperator, ISendMail mailer, IApplicationDeployService applicationDeployService, IReliableStateManager stateManager, StatefulServiceContext serviceContext, PartyCluster.ClusterService.ClusterConfig config ) : System	Creates a new instance of the service class.
GetClusterListAsync ( ) : Task>	Gets a list of all currently active clusters.
JoinClusterAsync ( int clusterId, string userEmail ) : Task	Processes a request to join a cluster.

Protected Methods

Method	Description
CreateServiceReplicaListeners ( ) : IEnumerable
OnOpenAsync ( ReplicaOpenMode openMode, CancellationToken cancellationToken ) : Task
RunAsync ( CancellationToken cancellationToken ) : Task	Main entry point for the service. This runs a continuous loop that manages the party clusters.

Private Methods

Method	Description
BalanceClustersAsync ( int target, CancellationToken cancellationToken ) : Task	Adds clusters by the given amount without going over the max threshold and without resulting in below the min threshold.
CodePackageActivationContext_ConfigurationPackageModifiedEvent ( object sender, PackageModifiedEventArgs e ) : void	Handler for config package updates.
CreateClusterId ( ) : int	Creates a new cluster ID.
CreateClusterInternalName ( ) : string	Creates a name for a cluster resource.
GetActiveClusters ( Cluster>.IReliableDictionary clusterDictionary, CancellationToken cancellationToken ) : Cluster>>>.Task	Gets a list of active clusters. Clusters that are new, being created, or ready and not expired are considered active.
GetTargetClusterCapacityAsync ( CancellationToken cancellationToken ) : Task	Determines how many clusters there should be based on user activity and min/max thresholds. When the user count goes below the low percent threshold, decrease capacity by (high - low)% When the user count goes above the high percent threshold, increase capacity by (1 - high)%
LoadConfigPackageAndSubscribe ( ) : void	Loads configuration settings from a config package named "Config" and subscribes to update events.
ProcessClusterStatusAsync ( PartyCluster.ClusterService.Cluster cluster ) : Task	Processes a cluster based on its current state.
ProcessClustersAsync ( CancellationToken cancellationToken ) : Task	Processes each cluster that is currently in the list of clusters managed by this service.
ProcessCreatingClusterAsync ( PartyCluster.ClusterService.Cluster cluster ) : Task	Processes a cluster in the "Creating" stage.
ProcessDeletingClusterAsync ( PartyCluster.ClusterService.Cluster cluster ) : Task	Processes a cluster that is in the "Deleting" stage.
ProcessNewClusterAsync ( PartyCluster.ClusterService.Cluster cluster ) : Task	Processes a new cluster.
ProcessReadyClusterAsync ( PartyCluster.ClusterService.Cluster cluster ) : Task	Processes clusters in the "Ready" stage.
ProcessRemoveClusterAsync ( PartyCluster.ClusterService.Cluster cluster ) : Task	Processes a cluster in the "Remove" stage.
UpdateClusterConfigSettings ( ConfigurationSettings settings ) : void	Updates the service's ClusterConfig instance with new settings from the given ConfigurationSettings.
