A low-level client representing Amazon Simple Workflow Service (SWF)
The Amazon Simple Workflow Service (Amazon SWF) makes it easy to build applications that use Amazon's cloud to coordinate work across distributed components. In Amazon SWF, a task represents a logical unit of work that is performed by a component of your workflow. Coordinating tasks in a workflow involves managing intertask dependencies, scheduling, and concurrency in accordance with the logical flow of the application.
Amazon SWF gives you full control over implementing tasks and coordinating them without worrying about underlying complexities such as tracking their progress and maintaining their state.
This documentation serves as reference only. For a broader overview of the Amazon SWF programming model, see the * Amazon SWF Developer Guide * .

Check if an operation can be paginated.
Returns the number of closed workflow executions within the given domain that meet the specified filtering criteria.
Note
This operation is eventually consistent. The results are best effort and may not exactly reflect recent updates and changes.
Access Control
You can use IAM policies to control this action's access to Amazon SWF resources as follows:
If the caller doesn't have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails. The associated event attribute's cause parameter is set to OPERATION_NOT_PERMITTED .

Executions of this workflow type need IAM roles to invoke Lambda functions. If you don't specify an IAM role when starting this workflow type, the default Lambda role is attached to the execution. For more information, see https://docs.aws.amazon.com/amazonswf/latest/developerguide/lambda-task.html in the Amazon SWF Developer Guide .
Exceptions
Create a paginator for an operation.
Returns an object that can wait for some condition.
Returns the history of the specified workflow execution. The results may be split into multiple pages. To retrieve subsequent pages, make the call again using the nextPageToken returned by the initial call.
Note
This operation is eventually consistent. The results are best effort and may not exactly reflect recent updates and changes.
Access Control
You can use IAM policies to control this action's access to Amazon SWF resources as follows:
If the caller doesn't have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails. The associated event attribute's cause parameter is set to OPERATION_NOT_PERMITTED . For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows in the Amazon SWF Developer Guide .

Request Syntax
response = client.get_workflow_execution_history(
domain='string',
execution={
'workflowId': 'string',
'runId': 'string'
},
nextPageToken='string',
maximumPageSize=123,
reverseOrder=True|False
)
[REQUIRED]
The name of the domain containing the workflow execution.
[REQUIRED]
Specifies the workflow execution for which to return the history.
The user defined identifier associated with the workflow execution.
A system-generated unique identifier for the workflow execution.
If NextPageToken is returned there are more results available. The value of NextPageToken is a unique pagination token for each page. Make the call again using the returned token to retrieve the next page. Keep all other arguments unchanged. Each pagination token expires after 60 seconds. Using an expired pagination token will return a 400 error: "Specified token has exceeded its maximum lifetime ".
The configured maximumPageSize determines how many results can be returned in a single call.

Because the number of workflow history events for a single workflow execution might be very large, the result returned might be split up across a number of pages. To retrieve subsequent pages, make additional calls to PollForDecisionTask using the nextPageToken returned by the initial call. Note that you do not call GetWorkflowExecutionHistory with this nextPageToken . Instead, call PollForDecisionTask again.
Access Control
You can use IAM policies to control this action's access to Amazon SWF resources as follows:
If the caller doesn't have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails. The associated event attribute's cause parameter is set to OPERATION_NOT_PERMITTED . For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows in the Amazon SWF Developer Guide .

Request Syntax
response = client.poll_for_decision_task(
domain='string',
taskList={
'name': 'string'
},
identity='string',
nextPageToken='string',
maximumPageSize=123,
reverseOrder=True|False
)
[REQUIRED]
The name of the domain containing the task lists to poll.
[REQUIRED]
Specifies the task list to poll for decision tasks.
The specified string must not start or end with whitespace. It must not contain a : (colon), / (slash), | (vertical bar), or any control characters (\u0000-\u001f | \u007f-\u009f ). Also, it must not be the literal string arn .
The name of the task list.
If NextPageToken is returned there are more results available. The value of NextPageToken is a unique pagination token for each page. Make the call again using the returned token to retrieve the next page. Keep all other arguments unchanged. Each pagination token expires after 60 seconds. Using an expired pagination token will return a 400 error: "Specified token has exceeded its maximum lifetime ".
The configured maximumPageSize determines how many results can be returned in a single call.
Note
The nextPageToken returned by this action cannot be used with GetWorkflowExecutionHistory to get the next page. You must call PollForDecisionTask again (with the nextPageToken ) to retrieve the next page of history records. Calling PollForDecisionTask with a nextPageToken doesn't return a new decision task.
The maximum number of results that are returned per call. Use nextPageToken to obtain further pages of results.
This is an upper limit only; the actual number of results returned per call may be fewer than the specified maximum.

Exceptions
Used by activity workers to report to the service that the ActivityTask represented by the specified taskToken is still making progress. The worker can also specify details of the progress, for example percent complete, using the details parameter. This action can also be used by the worker as a mechanism to check if cancellation is being requested for the activity task. If a cancellation is being attempted for the specified task, then the boolean cancelRequested flag returned by the service is set to true .
This action resets the taskHeartbeatTimeout clock. The taskHeartbeatTimeout is specified in RegisterActivityType .
This action doesn't in itself create an event in the workflow execution history. However, if the task times out, the workflow execution history contains a ActivityTaskTimedOut event that contains the information from the last heartbeat generated by the activity worker.
Note
The taskStartToCloseTimeout of an activity type is the maximum duration of an activity task, regardless of the number of RecordActivityTaskHeartbeat requests received. The taskStartToCloseTimeout is also specified in RegisterActivityType .
Note
This operation is only useful for long-lived activities to report liveliness of the task and to determine if a cancellation is being attempted.
Warning
If the cancelRequested flag returns true , a cancellation is being attempted. If the worker can cancel the activity, it should respond with RespondActivityTaskCanceled . Otherwise, it should ignore the cancellation request.
Access Control
You can use IAM policies to control this action's access to Amazon SWF resources as follows:
If the caller doesn't have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails. The associated event attribute's cause parameter is set to OPERATION_NOT_PERMITTED .

The duration is specified in seconds; an integer greater than or equal to 0. Unlike some of the other timeout parameters in Amazon SWF, you cannot specify a value of "NONE" for defaultExecutionStartToCloseTimeout ; there is a one-year max limit on the time that a workflow execution can run. Exceeding this limit always causes the workflow execution to time out.

Exceptions
Records a WorkflowExecutionCancelRequested event in the currently running workflow execution identified by the given domain, workflowId, and runId. This logically requests the cancellation of the workflow execution as a whole. It is up to the decider to take appropriate actions when it receives an execution history with this event.
Note
If the runId isn't specified, the WorkflowExecutionCancelRequested event is recorded in the history of the current open workflow execution with the specified workflowId in the domain.
Note
Because this action allows the workflow to properly clean up and gracefully close, it should be used instead of TerminateWorkflowExecution when possible.

The list of decisions (possibly empty) made by the decider while processing this decision task. See the docs for the Decision structure for details.
Specifies a decision made by the decider. A decision can be one of these types:
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
One of the following events might be added to the history to indicate an error. The event attribute's cause parameter indicates the cause. If cause is set to OPERATION_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 .
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.
Note
A workflow execution may be closed by the decider by returning one of the following decisions when completing a decision task: CompleteWorkflowExecution , FailWorkflowExecution , CancelWorkflowExecution and ContinueAsNewWorkflowExecution . An UnhandledDecision 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 call RespondDecisionTaskCompleted 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
You code a decision by first setting the decision type field to one of the above decision values, and then set the corresponding attributes field shown below:
Specifies the type of the decision.
Provides the details of the ScheduleActivityTask decision. It isn't set for other decision types.

Records a WorkflowExecutionTerminated event and forces closure of the workflow execution identified by the given domain, runId, and workflowId. The child policy, registered with the workflow type or specified when starting this execution, is applied to any open child workflow executions of this workflow execution.
Warning
If the identified workflow execution was in progress, it is terminated immediately.
Note
If a runId isn't specified, then the WorkflowExecutionTerminated event is recorded in the history of the current open workflow with the matching workflowId in the domain.
Note
You should consider using RequestCancelWorkflowExecution action instead because it allows the workflow to gracefully close while TerminateWorkflowExecution doesn't.
