public enum EventType

Fields

[OriginalName("EVENT_TYPE_ACTIVITY_PROPERTIES_MODIFIED_EXTERNALLY")] ActivityPropertiesModifiedExternally = 45

Some property or properties of an already-scheduled activity have changed by non-workflow code. The distinction of external vs. command-based modification is important so the SDK can maintain determinism when using the command-based approach.

Temporal Server has successfully Signaled the targeted Workflow

[OriginalName("EVENT_TYPE_MARKER_RECORDED")] MarkerRecorded = 25

A marker has been recorded. This event type is transparent to the Temporal Server The Server will only store it and will not try to understand it.

[OriginalName("EVENT_TYPE_REQUEST_CANCEL_EXTERNAL_WORKFLOW_EXECUTION_FAILED")] RequestCancelExternalWorkflowExecutionFailed = 23

Temporal Server could not cancel the targeted Workflow This is usually because the target Workflow could not be found

[OriginalName("EVENT_TYPE_REQUEST_CANCEL_EXTERNAL_WORKFLOW_EXECUTION_INITIATED")] RequestCancelExternalWorkflowExecutionInitiated = 22

Workflow has requested that the Temporal Server try to cancel another Workflow

[OriginalName("EVENT_TYPE_SIGNAL_EXTERNAL_WORKFLOW_EXECUTION_FAILED")] SignalExternalWorkflowExecutionFailed = 38

Temporal Server cannot Signal the targeted Workflow Usually because the Workflow could not be found

[OriginalName("EVENT_TYPE_SIGNAL_EXTERNAL_WORKFLOW_EXECUTION_INITIATED")] SignalExternalWorkflowExecutionInitiated = 37

Temporal Server will try to Signal the targeted Workflow Contains the Signal name, as well as a Signal payload

[OriginalName("EVENT_TYPE_START_CHILD_WORKFLOW_EXECUTION_FAILED")] StartChildWorkflowExecutionFailed = 30

Child Workflow execution cannot be started/triggered Usually due to a child Workflow ID collision

[OriginalName("EVENT_TYPE_START_CHILD_WORKFLOW_EXECUTION_INITIATED")] StartChildWorkflowExecutionInitiated = 29

Temporal Server will try to start a child Workflow

[OriginalName("EVENT_TYPE_TIMER_CANCELED")] TimerCanceled = 19

A time has been cancelled

[OriginalName("EVENT_TYPE_TIMER_FIRED")] TimerFired = 18

A timer has fired

[OriginalName("EVENT_TYPE_TIMER_STARTED")] TimerStarted = 17

A timer has started

Place holder and should never appear in a Workflow execution history

[OriginalName("EVENT_TYPE_UPSERT_WORKFLOW_SEARCH_ATTRIBUTES")] UpsertWorkflowSearchAttributes = 40

[OriginalName("EVENT_TYPE_WORKFLOW_EXECUTION_CANCEL_REQUESTED")] WorkflowExecutionCancelRequested = 20

A request has been made to cancel the Workflow execution

[OriginalName("EVENT_TYPE_WORKFLOW_EXECUTION_CANCELED")] WorkflowExecutionCanceled = 21

SDK client has confirmed the cancellation request and the Workflow execution has been cancelled
