Event within a workflow execution. A history event can be one of these types:
- WorkflowExecutionStarted: The workflow execution was started.
- WorkflowExecutionCompleted: The workflow execution was closed due to successful completion.
- WorkflowExecutionFailed: The workflow execution closed due to a failure.
- WorkflowExecutionTimedOut: The workflow execution was closed because a time out was exceeded.
- WorkflowExecutionCanceled: The workflow execution was successfully canceled and closed.
- WorkflowExecutionTerminated: The workflow execution was terminated.
- WorkflowExecutionContinuedAsNew: The workflow execution was closed and a new execution of the same type was created with the same workflowId.
- WorkflowExecutionCancelRequested: A request to cancel this workflow execution was made.
- DecisionTaskScheduled: A decision task was scheduled for the workflow execution.
- DecisionTaskStarted: The decision task was dispatched to a decider.
- DecisionTaskCompleted: The decider successfully completed a decision task by calling RespondDecisionTaskCompleted.
- DecisionTaskTimedOut: The decision task timed out.
- ActivityTaskScheduled: An activity task was scheduled for execution.
- ScheduleActivityTaskFailed: Failed to process ScheduleActivityTask decision. This happens when the decision is not configured properly, for example the activity type specified is not registered.
- ActivityTaskStarted: The scheduled activity task was dispatched to a worker.
- ActivityTaskCompleted: An activity worker successfully completed an activity task by calling RespondActivityTaskCompleted.
- ActivityTaskFailed: An activity worker failed an activity task by calling RespondActivityTaskFailed.
- ActivityTaskTimedOut: The activity task timed out.
- ActivityTaskCanceled: The activity task was successfully canceled.
- ActivityTaskCancelRequested: A RequestCancelActivityTask decision was received by the system.
- RequestCancelActivityTaskFailed: Failed to process RequestCancelActivityTask decision. This happens when the decision is not configured properly.
- WorkflowExecutionSignaled: An external signal was received for the workflow execution.
- MarkerRecorded: A marker was recorded in the workflow history as the result of a RecordMarker decision.
- TimerStarted: A timer was started for the workflow execution due to a StartTimer decision.
- StartTimerFailed: Failed to process StartTimer decision. This happens when the decision is not configured properly, for example a timer already exists with the specified timer ID.
- TimerFired: A timer, previously started for this workflow execution, fired.
- TimerCanceled: A timer, previously started for this workflow execution, was successfully canceled.
- CancelTimerFailed: Failed to process CancelTimer decision. This happens when the decision is not configured properly, for example no timer exists with the specified timer ID.
- StartChildWorkflowExecutionInitiated: A request was made to start a child workflow execution.
- StartChildWorkflowExecutionFailed: Failed to process StartChildWorkflowExecution decision. This happens when the decision is not configured properly, for example the workflow type specified is not registered.
- ChildWorkflowExecutionStarted: A child workflow execution was successfully started.
- 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.
- ChildWorkflowExecutionTimedOut: A child workflow execution, started by this workflow execution, timed out and was closed.
- ChildWorkflowExecutionCanceled: A child workflow execution, started by this workflow execution, was canceled and closed.
- ChildWorkflowExecutionTerminated: A child workflow execution, started by this workflow execution, was terminated.
- SignalExternalWorkflowExecutionInitiated: A request to signal an external workflow was made.
- ExternalWorkflowExecutionSignaled: A signal, requested by this workflow execution, was successfully delivered to the target external workflow execution.
- SignalExternalWorkflowExecutionFailed: The request to signal an external workflow execution failed.
- RequestCancelExternalWorkflowExecutionInitiated: A request was made to request the cancellation of an external workflow execution.
- ExternalWorkflowExecutionCancelRequested: Request to cancel an external workflow execution was successfully delivered to the target execution.
- RequestCancelExternalWorkflowExecutionFailed: Request to cancel an external workflow execution failed.
- LambdaFunctionScheduled: An AWS Lambda function was scheduled for execution.
- LambdaFunctionStarted: The scheduled function was invoked in the AWS Lambda service.
- LambdaFunctionCompleted: The AWS Lambda function successfully completed.
- LambdaFunctionFailed: The AWS Lambda function execution failed.
- LambdaFunctionTimedOut: The AWS Lambda function execution timed out.
- ScheduleLambdaFunctionFailed: Failed to process ScheduleLambdaFunction decision. This happens when the workflow execution does not have the proper IAM role attached to invoke AWS Lambda functions.
- StartLambdaFunctionFailed: Failed to invoke the scheduled function in the AWS Lambda service. This happens when the AWS Lambda service is not available in the current region, or received too many requests.
