Constructors

StatefulServiceBase(StatefulServiceContext, IStateProviderReplica) StatefulServiceBase(StatefulServiceContext, IStateProviderReplica) StatefulServiceBase(StatefulServiceContext, IStateProviderReplica)

Initializes a new instance of the StatefulServiceBase class.

Properties

Context Context Context

Gets the service context that this stateful service is operating under. It provides information like replica ID, partition ID, service name etc.

Partition Partition Partition

Gets the service partition to which current service replica belongs.

Methods

BackupAsync(BackupDescription) BackupAsync(BackupDescription) BackupAsync(BackupDescription)

Performs a backup of all reliable state managed by this StatefulServiceBase.

BackupAsync(BackupDescription, TimeSpan, CancellationToken) BackupAsync(BackupDescription, TimeSpan, CancellationToken) BackupAsync(BackupDescription, TimeSpan, CancellationToken)

Performs a backup of all reliable state managed by this StatefulServiceBase.

CreateServiceReplicaListeners() CreateServiceReplicaListeners() CreateServiceReplicaListeners()

Override this method to supply the communication listeners for the service replica. The endpoints returned by the communication listener are stored as a JSON string of ListenerName, Endpoint string pairs like

{"Endpoints":{"Listener1":"Endpoint1","Listener2":"Endpoint2" ...}}

GetAddresses() GetAddresses() GetAddresses()

Gets the list of all the addresses for this service replica as (ListenerName, Endpoint) key-value pair.

OnAbort() OnAbort() OnAbort()

The notification that the service is being aborted. RunAsync MAY be running concurrently with the execution of this method, as cancellation is not awaited on the abort path.

OnChangeRoleAsync(ReplicaRole, CancellationToken) OnChangeRoleAsync(ReplicaRole, CancellationToken) OnChangeRoleAsync(ReplicaRole, CancellationToken)

This method is called when role of the replica is changing and it is the final step before completing ChangeRoleAsync(ReplicaRole, CancellationToken). Override this method to be notified that ChangeRole has completed for this replica's internal components.

OnCloseAsync(CancellationToken) OnCloseAsync(CancellationToken) OnCloseAsync(CancellationToken)

This method is called as the final step of closing the service gracefully. Override this method to be notified that Close has completed for this replica's internal components.

OnDataLossAsync(RestoreContext, CancellationToken) OnDataLossAsync(RestoreContext, CancellationToken) OnDataLossAsync(RestoreContext, CancellationToken)

This method is called during suspected data loss. You can override this method to restore the service in case of data loss.

OnOpenAsync(ReplicaOpenMode, CancellationToken) OnOpenAsync(ReplicaOpenMode, CancellationToken) OnOpenAsync(ReplicaOpenMode, CancellationToken)

This method is called when the replica is being opened and it is the final step of opening the service. Override this method to be notified that Open has completed for this replica's internal components.

OnRestoreCompletedAsync(CancellationToken) OnRestoreCompletedAsync(CancellationToken) OnRestoreCompletedAsync(CancellationToken)

This method is called when replica's state has been restored successfully via the Backup Restore service. This is only supported when the reliable state provider replica object passed in the constructor is derived from IStateProviderReplica2.

RunAsync(CancellationToken) RunAsync(CancellationToken) RunAsync(CancellationToken)

This method is implemented as a processing loop and will only be called when the replica is primary with write status. Override this method with the application logic.
