HistoryEvent class

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.
