Respond Decision Task Completed
swf_respond_decision_task_completed | R Documentation |
Used by deciders to tell the service that the DecisionTask identified by the taskToken has successfully completed¶
Description¶
Used by deciders to tell the service that the DecisionTask identified by
the taskToken
has successfully completed. The decisions
argument
specifies the list of decisions made while processing the task.
A DecisionTaskCompleted
event is added to the workflow history. The
executionContext
specified is attached to the event in the workflow
execution history.
Access Control
If an IAM policy grants permission to use
respond_decision_task_completed
, it can express permissions for the
list of decisions in the decisions
parameter. Each of the decisions
has one or more parameters, much like a regular API call. To allow for
policies to be as readable as possible, you can express permissions on
decisions as if they were actual API calls, including applying
conditions to some parameters. For more information, see Using IAM to
Manage Access to Amazon SWF
Workflows
in the Amazon SWF Developer Guide.
Usage¶
swf_respond_decision_task_completed(taskToken, decisions,
executionContext, taskList, taskListScheduleToStartTimeout)
Arguments¶
taskToken
[required] The
taskToken
from the DecisionTask.taskToken
is generated by the service and should be treated as an opaque value. If the task is passed to another process, itstaskToken
must also be passed. This enables it to provide its progress and respond with results.decisions
The list of decisions (possibly empty) made by the decider while processing this decision task. See the docs for the Decision structure for details.
executionContext
User defined context to add to workflow execution.
taskList
The task list to use for the future decision tasks of this workflow execution. This list overrides the original task list you specified while starting the workflow execution.
taskListScheduleToStartTimeout
Specifies a timeout (in seconds) for the task list override. When this parameter is missing, the task list override is permanent. This parameter makes it possible to temporarily override the task list. If a decision task scheduled on the override task list is not started within the timeout, the decision task will time out. Amazon SWF will revert the override and schedule a new decision task to the original task list.
If a decision task scheduled on the override task list is started within the timeout, but not completed within the start-to-close timeout, Amazon SWF will also revert the override and schedule a new decision task to the original task list.
Value¶
An empty list.
