Module Values.HistoryEventSource

Event within a workflow execution. A history event can be one of these types: ActivityTaskCancelRequested – A RequestCancelActivityTask decision was received by the system. ActivityTaskCanceled – The activity task was successfully canceled. ActivityTaskCompleted – An activity worker successfully completed an activity task by calling RespondActivityTaskCompleted. ActivityTaskFailed – An activity worker failed an activity task by calling RespondActivityTaskFailed. ActivityTaskScheduled – An activity task was scheduled for execution. ActivityTaskStarted – The scheduled activity task was dispatched to a worker. ActivityTaskTimedOut – The activity task timed out. CancelTimerFailed – Failed to process CancelTimer decision. This happens when the decision isn't configured properly, for example no timer exists with the specified timer Id. CancelWorkflowExecutionFailed – A request to cancel a workflow execution failed. ChildWorkflowExecutionCanceled – A child workflow execution, started by this workflow execution, was canceled and closed. ChildWorkflowExecutionCompleted – A child workflow execution, started by this workflow execution, completed successfully and was closed. ChildWorkflowExecutionFailed – A child workflow execution, started by this workflow execution, failed to complete successfully and was closed. ChildWorkflowExecutionStarted – A child workflow execution was successfully started. ChildWorkflowExecutionTerminated – A child workflow execution, started by this workflow execution, was terminated. ChildWorkflowExecutionTimedOut – A child workflow execution, started by this workflow execution, timed out and was closed. CompleteWorkflowExecutionFailed – The workflow execution failed to complete. ContinueAsNewWorkflowExecutionFailed – The workflow execution failed to complete after being continued as a new workflow execution. DecisionTaskCompleted – The decider successfully completed a decision task by calling RespondDecisionTaskCompleted. DecisionTaskScheduled – A decision task was scheduled for the workflow execution. DecisionTaskStarted – The decision task was dispatched to a decider. DecisionTaskTimedOut – The decision task timed out. ExternalWorkflowExecutionCancelRequested – Request to cancel an external workflow execution was successfully delivered to the target execution. ExternalWorkflowExecutionSignaled – A signal, requested by this workflow execution, was successfully delivered to the target external workflow execution. FailWorkflowExecutionFailed – A request to mark a workflow execution as failed, itself failed. MarkerRecorded – A marker was recorded in the workflow history as the result of a RecordMarker decision. RecordMarkerFailed – A RecordMarker decision was returned as failed. RequestCancelActivityTaskFailed – Failed to process RequestCancelActivityTask decision. This happens when the decision isn't configured properly. RequestCancelExternalWorkflowExecutionFailed – Request to cancel an external workflow execution failed. RequestCancelExternalWorkflowExecutionInitiated – A request was made to request the cancellation of an external workflow execution. ScheduleActivityTaskFailed – Failed to process ScheduleActivityTask decision. This happens when the decision isn't configured properly, for example the activity type specified isn't registered. SignalExternalWorkflowExecutionFailed – The request to signal an external workflow execution failed. SignalExternalWorkflowExecutionInitiated – A request to signal an external workflow was made. StartActivityTaskFailed – A scheduled activity task failed to start. StartChildWorkflowExecutionFailed – Failed to process StartChildWorkflowExecution decision. This happens when the decision isn't configured properly, for example the workflow type specified isn't registered. StartChildWorkflowExecutionInitiated – A request was made to start a child workflow execution. StartTimerFailed – Failed to process StartTimer decision. This happens when the decision isn't configured properly, for example a timer already exists with the specified timer Id. TimerCanceled – A timer, previously started for this workflow execution, was successfully canceled. TimerFired – A timer, previously started for this workflow execution, fired. TimerStarted – A timer was started for the workflow execution due to a StartTimer decision. WorkflowExecutionCancelRequested – A request to cancel this workflow execution was made. WorkflowExecutionCanceled – The workflow execution was successfully canceled and closed. WorkflowExecutionCompleted – The workflow execution was closed due to successful completion. WorkflowExecutionContinuedAsNew – The workflow execution was closed and a new execution of the same type was created with the same workflowId. WorkflowExecutionFailed – The workflow execution closed due to a failure. WorkflowExecutionSignaled – An external signal was received for the workflow execution. WorkflowExecutionStarted – The workflow execution was started. WorkflowExecutionTerminated – The workflow execution was terminated. WorkflowExecutionTimedOut – The workflow execution was closed because a time out was exceeded.
