event.Specifies a decision made by the decider. A decision can be one of these types:
-
CancelTimer
– Cancels a previously started timer and records aTimerCanceled
event in the history. -

– Closes the workflow execution and records aWorkflowExecutionCanceled
event in the history. -
CompleteWorkflowExecution
– Closes the workflow execution and records aWorkflowExecutionCompleted
event in the history . -

– Closes the workflow execution and starts a new workflow execution of the same type using the same workflow ID and a unique run Id. AWorkflowExecutionContinuedAsNew
event is recorded in the history. -
FailWorkflowExecution
– Closes the workflow execution and records aWorkflowExecutionFailed
event in the history. -

RequestCancelActivityTask

If the activity task was already assigned to a worker, then the worker is informed that cancellation has been requested in the response toRecordActivityTaskHeartbeat
. -

event in the history. -

StartTimer
– Starts a timer for this workflow execution and records aTimerStarted
event in the history. This timer fires after the specified delay and record aTimerFired
event.
Access Control
If you grant permission to use
RespondDecisionTaskCompleted
, you can use IAM policies to express permissions for the list of decisions returned by this action as if they were members of the API. Treating decisions as a pseudo API maintains a uniform conceptual model and helps keep policies readable. For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows in the Amazon SWF Developer Guide.Decision Failure
Decisions can fail for several reasons
-
The ordering of decisions should follow a logical flow. Some decisions might not make sense in the current context of the workflow execution and therefore fails.
-
A limit on your account was reached.
-
The decision lacks sufficient permissions.
One of the following events might be added to the history to indicate an error. The event attribute's
cause
parameter indicates the cause. Ifcause
is set toOPERATION_NOT_PERMITTED
, the decision failed because it lacked sufficient permissions. For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows in the Amazon SWF Developer Guide.-
ScheduleActivityTaskFailed
– AScheduleActivityTask
decision failed. This could happen if the activity type specified in the decision isn't registered, is in a deprecated state, or the decision isn't properly configured. -
RequestCancelActivityTaskFailed
– ARequestCancelActivityTask
decision failed. This could happen if there is no open activity task with the specified activityId. -
StartTimerFailed
– AStartTimer
decision failed. This could happen if there is another open timer with the same timerId. -
CancelTimerFailed
– ACancelTimer
decision failed. This could happen if there is no open timer with the specified timerId. -
StartChildWorkflowExecutionFailed
– AStartChildWorkflowExecution
decision failed. This could happen if the workflow type specified isn't registered, is deprecated, or the decision isn't properly configured. -
SignalExternalWorkflowExecutionFailed
– ASignalExternalWorkflowExecution
decision failed. This could happen if theworkflowID
specified in the decision was incorrect. -
RequestCancelExternalWorkflowExecutionFailed
– ARequestCancelExternalWorkflowExecution
decision failed. This could happen if theworkflowID
specified in the decision was incorrect. -
CancelWorkflowExecutionFailed
– ACancelWorkflowExecution
decision failed. This could happen if there is an unhandled decision task pending in the workflow execution. -
CompleteWorkflowExecutionFailed
– ACompleteWorkflowExecution
decision failed. This could happen if there is an unhandled decision task pending in the workflow execution. -
ContinueAsNewWorkflowExecutionFailed
– AContinueAsNewWorkflowExecution
decision failed. This could happen if there is an unhandled decision task pending in the workflow execution or the ContinueAsNewWorkflowExecution decision was not configured correctly. -
FailWorkflowExecutionFailed
– AFailWorkflowExecution
decision failed. This could happen if there is an unhandled decision task pending in the workflow execution.
The preceding error events might occur due to an error in the decider logic, which might put the workflow execution in an unstable state The cause field in the event structure for the error event indicates the cause of the error.
A workflow execution may be closed by the decider by returning one of the following decisions when completing a decision task:
CompleteWorkflowExecution
,FailWorkflowExecution
,CancelWorkflowExecution
andContinueAsNewWorkflowExecution
. AnUnhandledDecision
fault is returned if a workflow closing decision is specified and a signal or activity event had been added to the history while the decision task was being performed by the decider. Unlike the above situations which are logic issues, this fault is always possible because of race conditions in a distributed system. The right action here is to callRespondDecisionTaskCompleted
without any decisions. This would result in another decision task with these new events included in the history. The decider should handle the new events and may decide to close the workflow execution.How to Code a Decision
