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.
