Types

type CreateOrchestrationAction

type CreateOrchestrationAction = protos.CreateOrchestrationAction

const (
	REUSE_ID_ACTION_ERROR     CreateOrchestrationAction = protos.CreateOrchestrationAction_ERROR
	REUSE_ID_ACTION_IGNORE    CreateOrchestrationAction = protos.CreateOrchestrationAction_IGNORE
	REUSE_ID_ACTION_TERMINATE CreateOrchestrationAction = protos.CreateOrchestrationAction_TERMINATE
)

type FetchOrchestrationMetadataOptions

type FetchOrchestrationMetadataOptions func(*protos.GetInstanceRequest)

GetOrchestrationMetadataOptions is a set of options for fetching orchestration metadata.

func WithFetchPayloads

func WithFetchPayloads(fetchPayloads bool) FetchOrchestrationMetadataOptions

WithFetchPayloads configures whether to load orchestration inputs, outputs, and custom status values, which could be large.

type InstanceID

type InstanceID string

InstanceID is a unique identifier for an orchestration instance.

type NewOrchestrationOptions

type NewOrchestrationOptions func(*protos.CreateInstanceRequest) error

NewOrchestrationOptions configures options for starting a new orchestration.

func WithInput

func WithInput(input any) NewOrchestrationOptions

WithInput configures an input for the orchestration. The specified input must be serializable.

func WithInstanceID

func WithInstanceID(id InstanceID) NewOrchestrationOptions

WithOrchestrationIdReusePolicy configures Orchestration ID reuse policy.

func WithRawInput

func WithRawInput(rawInput *wrapperspb.StringValue) NewOrchestrationOptions

WithRawInput configures an input for the orchestration. The specified input must be a string.

func WithStartTime

func WithStartTime(startTime time.Time) NewOrchestrationOptions

WithStartTime configures a start time at which the orchestration should start running. Note that the actual start time could be later than the specified start time if the task hub is under load or if the app is not running at the specified start time.
