Types

type Actors

type Actors struct {
	// contains filtered or unexported fields
}

func New

func New(opts Options) (*Actors, error)

func (*Actors) AbandonActivityWorkItem

func (*Actors) AbandonActivityWorkItem(ctx context.Context, wi *backend.ActivityWorkItem) error

AbandonActivityWorkItem implements backend.Backend. It gets called by durabletask-go when there is an unexpected failure in the workflow activity execution pipeline.

func (*Actors) AbandonOrchestrationWorkItem

func (*Actors) AbandonOrchestrationWorkItem(ctx context.Context, wi *backend.OrchestrationWorkItem) error

AbandonOrchestrationWorkItem implements backend.Backend. It gets called by durabletask-go when there is an unexpected failure in the workflow orchestration execution pipeline.

func (*Actors) AddNewOrchestrationEvent

func (abe *Actors) AddNewOrchestrationEvent(ctx context.Context, id api.InstanceID, e *backend.HistoryEvent) error

AddNewOrchestrationEvent implements backend.Backend and sends the event e to the workflow actor identified by id.

func (*Actors) CompleteActivityWorkItem

func (*Actors) CompleteActivityWorkItem(ctx context.Context, wi *backend.ActivityWorkItem) error

CompleteActivityWorkItem implements backend.Backend

func (*Actors) CompleteOrchestrationWorkItem

func (*Actors) CompleteOrchestrationWorkItem(ctx context.Context, wi *backend.OrchestrationWorkItem) error

CompleteOrchestrationWorkItem implements backend.Backend

func (*Actors) CreateOrchestrationInstance

func (abe *Actors) CreateOrchestrationInstance(ctx context.Context, e *backend.HistoryEvent, opts ...backend.OrchestrationIdReusePolicyOptions) error

CreateOrchestrationInstance implements backend.Backend and creates a new workflow instance.

Internally, creating a workflow instance also creates a new actor with the same ID. The create request is saved into the actor's "inbox" and then executed via a reminder thread. If the app is scaled out across multiple replicas, the actor might get assigned to a replicas other than this one.

func (*Actors) CreateTaskHub

func (*Actors) CreateTaskHub(context.Context) error

CreateTaskHub implements backend.Backend

func (*Actors) DeleteTaskHub

func (*Actors) DeleteTaskHub(context.Context) error

DeleteTaskHub implements backend.Backend

func (*Actors) GetOrchestrationMetadata

func (abe *Actors) GetOrchestrationMetadata(ctx context.Context, id api.InstanceID) (*backend.OrchestrationMetadata, error)

GetOrchestrationMetadata implements backend.Backend

func (*Actors) GetOrchestrationRuntimeState

func (abe *Actors) GetOrchestrationRuntimeState(ctx context.Context, owi *backend.OrchestrationWorkItem) (*backend.OrchestrationRuntimeState, error)

GetOrchestrationRuntimeState implements backend.Backend

func (*Actors) NextActivityWorkItem

func (abe *Actors) NextActivityWorkItem(ctx context.Context) (*backend.ActivityWorkItem, error)

NextActivityWorkItem implements backend.Backend

func (*Actors) NextOrchestrationWorkItem

func (abe *Actors) NextOrchestrationWorkItem(ctx context.Context) (*backend.OrchestrationWorkItem, error)

NextOrchestrationWorkItem implements backend.Backend

func (*Actors) PurgeOrchestrationState

func (abe *Actors) PurgeOrchestrationState(ctx context.Context, id api.InstanceID) error

PurgeOrchestrationState deletes all saved state for the specific orchestration instance.

func (*Actors) RegisterActors

func (abe *Actors) RegisterActors(ctx context.Context) error

func (*Actors) Start

func (abe *Actors) Start(ctx context.Context) error

Start implements backend.Backend

func (*Actors) Stop

func (*Actors) Stop(context.Context) error

Stop implements backend.Backend

func (*Actors) String

func (abe *Actors) String() string

String displays the type information

func (*Actors) UnRegisterActors

func (abe *Actors) UnRegisterActors(ctx context.Context) error

func (*Actors) WatchOrchestrationRuntimeStatus

func (abe *Actors) WatchOrchestrationRuntimeStatus(ctx context.Context, id api.InstanceID, ch chan<- *backend.OrchestrationMetadata) error

type Options

	AppID              string
	Namespace          string
