DESCRIPTION

Amazon Simple Workflow Service

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.

METHODS

CountClosedWorkflowExecutions(Domain => Str, [CloseStatusFilter => Paws::SimpleWorkflow::CloseStatusFilter, CloseTimeFilter => Paws::SimpleWorkflow::ExecutionTimeFilter, ExecutionFilter => Paws::SimpleWorkflow::WorkflowExecutionFilter, StartTimeFilter => Paws::SimpleWorkflow::ExecutionTimeFilter, TagFilter => Paws::SimpleWorkflow::TagFilter, TypeFilter => Paws::SimpleWorkflow::WorkflowTypeFilter])

Each argument is described in detail in: Paws::SimpleWorkflow::CountClosedWorkflowExecutions

Returns: a Paws::SimpleWorkflow::WorkflowExecutionCount instance

Returns the number of closed workflow executions within the given
domain that meet the specified filtering criteria.

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:

Use a Resource element with the domain name to limit the action to only specified domains.
Use an Action element to allow or deny permission to call this action.
Constrain the following parameters by using a Condition element with the appropriate keys.
- tagFilter.tag: String constraint. The key is swf:tagFilter.tag.
- typeFilter.name: String constraint. The key is swf:typeFilter.name.
- typeFilter.version: String constraint. The key is swf:typeFilter.version.

If the caller does not 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 will be set to OPERATION_NOT_PERMITTED. For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows.

Use an Action element to allow or deny permission to call this action.
You cannot use an IAM policy to constrain this action's parameters.

PollForActivityTask(Domain => Str, TaskList => Paws::SimpleWorkflow::TaskList, [Identity => Str])

Each argument is described in detail in: Paws::SimpleWorkflow::PollForActivityTask

Returns: a Paws::SimpleWorkflow::ActivityTask instance

Used by workers to get an ActivityTask from the specified activity
C<taskList>. This initiates a long poll, where the service holds the
HTTP connection open and responds as soon as a task becomes available.
The maximum time the service holds on to the request before responding
is 60 seconds. If no task is available within 60 seconds, the poll will
return an empty result. An empty result, in this context, means that an
ActivityTask is returned, but that the value of taskToken is an empty
string. If a task is returned, the worker should use its type to
identify and process it correctly.

Workers should set their client side socket timeout to at least 70 seconds (10 seconds higher than the maximum time service may hold the poll request).

Access Control

You can use IAM policies to control this action's access to Amazon SWF resources as follows:

Use a Resource element with the domain name to limit the action to only specified domains.
Use an Action element to allow or deny permission to call this action.
Constrain the taskList.name parameter by using a Condition element with the swf:taskList.name key to allow the action to access only certain task lists.

PollForDecisionTask(Domain => Str, TaskList => Paws::SimpleWorkflow::TaskList, [Identity => Str, MaximumPageSize => Int, NextPageToken => Str, ReverseOrder => Bool])

Each argument is described in detail in: Paws::SimpleWorkflow::PollForDecisionTask

Returns: a Paws::SimpleWorkflow::DecisionTask instance

Used by deciders to get a DecisionTask from the specified decision
C<taskList>. A decision task may be returned for any open workflow
execution that is using the specified task list. The task includes a
paginated view of the history of the workflow execution. The decider
should use the workflow type and the history to determine how to
properly handle the task.

This action initiates a long poll, where the service holds the HTTP connection open and responds as soon a task becomes available. If no decision task is available in the specified task list before the timeout of 60 seconds expires, an empty result is returned. An empty result, in this context, means that a DecisionTask is returned, but that the value of taskToken is an empty string.

Deciders should set their client-side socket timeout to at least 70 seconds (10 seconds higher than the timeout). 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:

Use a Resource element with the domain name to limit the action to only specified domains.
Use an Action element to allow or deny permission to call this action.
Constrain the taskList.name parameter by using a Condition element with the swf:taskList.name key to allow the action to access only certain task lists.

RecordActivityTaskHeartbeat(TaskToken => Str, [Details => Str])

Each argument is described in detail in: Paws::SimpleWorkflow::RecordActivityTaskHeartbeat

Returns: a Paws::SimpleWorkflow::ActivityTaskStatus instance

Used by activity workers to report to the service that the ActivityTask
represented by the specified C<taskToken> is still making progress. The
worker can also (optionally) specify details of the progress, for
example percent complete, using the C<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 C<cancelRequested>
flag returned by the service is set to C<true>.

This action resets the taskHeartbeatTimeout clock. The taskHeartbeatTimeout is specified in RegisterActivityType.

This action does not in itself create an event in the workflow execution history. However, if the task times out, the workflow execution history will contain a ActivityTaskTimedOut event that contains the information from the last heartbeat generated by the activity worker.

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. This operation is only useful for long-lived activities to report liveliness of the task and to determine if a cancellation is being attempted. 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:

Use a Resource element with the domain name to limit the action to only specified domains.
Use an Action element to allow or deny permission to call this action.
You cannot use an IAM policy to constrain this action's parameters.

RegisterActivityType(Domain => Str, Name => Str, Version => Str, [DefaultTaskHeartbeatTimeout => Str, DefaultTaskList => Paws::SimpleWorkflow::TaskList, DefaultTaskPriority => Str, DefaultTaskScheduleToCloseTimeout => Str, DefaultTaskScheduleToStartTimeout => Str, DefaultTaskStartToCloseTimeout => Str, Description => Str])

Each argument is described in detail in: Paws::SimpleWorkflow::RegisterActivityType

Returns: nothing

Registers a new I<activity type> along with its configuration settings
in the specified domain.

A TypeAlreadyExists fault is returned if the type already exists in the domain. You cannot change any configuration settings of the type after its registration, and it must be registered as a new version.

Access Control

You can use IAM policies to control this action's access to Amazon SWF resources as follows:

Use a Resource element with the domain name to limit the action to only specified domains.
Use an Action element to allow or deny permission to call this action.

- defaultTaskList.name: String constraint. The key is swf:defaultTaskList.name.
- name: String constraint. The key is swf:name.
- version: String constraint. The key is swf:version.

RegisterDomain(Name => Str, WorkflowExecutionRetentionPeriodInDays => Str, [Description => Str])

Each argument is described in detail in: Paws::SimpleWorkflow::RegisterDomain

Returns: nothing

Registers a new domain.

Access Control

You can use IAM policies to control this action's access to Amazon SWF resources as follows:

You cannot use an IAM policy to control domain access for this action. The name of the domain being registered is available as the resource of this action.
Use an Action element to allow or deny permission to call this action.
You cannot use an IAM policy to constrain this action's parameters.

RegisterWorkflowType(Domain => Str, Name => Str, Version => Str, [DefaultChildPolicy => Str, DefaultExecutionStartToCloseTimeout => Str, DefaultLambdaRole => Str, DefaultTaskList => Paws::SimpleWorkflow::TaskList, DefaultTaskPriority => Str, DefaultTaskStartToCloseTimeout => Str, Description => Str])

Each argument is described in detail in: Paws::SimpleWorkflow::RegisterWorkflowType

Returns: nothing

Registers a new I<workflow type> and its configuration settings in the
specified domain.

The retention period for the workflow history is set by the RegisterDomain action.

If the type already exists, then a TypeAlreadyExists fault is returned. You cannot change the configuration settings of a workflow type once it is registered and it must be registered as a new version.

Access Control

You can use IAM policies to control this action's access to Amazon SWF resources as follows:

Use a Resource element with the domain name to limit the action to only specified domains.
Use an Action element to allow or deny permission to call this action.
Constrain the following parameters by using a Condition element with the appropriate keys.
- defaultTaskList.name: String constraint. The key is swf:defaultTaskList.name.
- name: String constraint. The key is swf:name.
- version: String constraint. The key is swf:version.

RequestCancelWorkflowExecution(Domain => Str, WorkflowId => Str, [RunId => Str])

Each argument is described in detail in: Paws::SimpleWorkflow::RequestCancelWorkflowExecution

Returns: nothing

Records a C<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.

If the runId is not specified, the WorkflowExecutionCancelRequested event is recorded in the history of the current open workflow execution with the specified workflowId in the domain. Because this action allows the workflow to properly clean up and gracefully close, it should be used instead of TerminateWorkflowExecution when possible.

Access Control

You can use IAM policies to control this action's access to Amazon SWF resources as follows:

Use a Resource element with the domain name to limit the action to only specified domains.
Use an Action element to allow or deny permission to call this action.
You cannot use an IAM policy to constrain this action's parameters.

RespondActivityTaskCanceled(TaskToken => Str, [Details => Str])

Each argument is described in detail in: Paws::SimpleWorkflow::RespondActivityTaskCanceled

Returns: nothing

Used by workers to tell the service that the ActivityTask identified by
the C<taskToken> was successfully canceled. Additional C<details> can
be optionally provided using the C<details> argument.

These details (if provided) appear in the ActivityTaskCanceled event added to the workflow history.

Only use this operation if the canceled flag of a RecordActivityTaskHeartbeat request returns true and if the activity can be safely undone or abandoned.

A task is considered open from the time that it is scheduled until it is closed. Therefore a task is reported as open while a worker is processing it. A task is closed after it has been specified in a call to RespondActivityTaskCompleted, RespondActivityTaskCanceled, RespondActivityTaskFailed, or the task has timed out.

Access Control

You can use IAM policies to control this action's access to Amazon SWF resources as follows:

Use a Resource element with the domain name to limit the action to only specified domains.
Use an Action element to allow or deny permission to call this action.
You cannot use an IAM policy to constrain this action's parameters.

RespondActivityTaskCompleted(TaskToken => Str, [Result => Str])

Each argument is described in detail in: Paws::SimpleWorkflow::RespondActivityTaskCompleted

Returns: nothing

Used by workers to tell the service that the ActivityTask identified by
the C<taskToken> completed successfully with a C<result> (if provided).
The C<result> appears in the C<ActivityTaskCompleted> event in the
workflow history.

If the requested task does not complete successfully, use RespondActivityTaskFailed instead. If the worker finds that the task is canceled through the canceled flag returned by RecordActivityTaskHeartbeat, it should cancel the task, clean up and then call RespondActivityTaskCanceled.

Access Control

You can use IAM policies to control this action's access to Amazon SWF resources as follows:

Use a Resource element with the domain name to limit the action to only specified domains.
Use an Action element to allow or deny permission to call this action.
You cannot use an IAM policy to constrain this action's parameters.

RespondActivityTaskFailed(TaskToken => Str, [Details => Str, Reason => Str])

Each argument is described in detail in: Paws::SimpleWorkflow::RespondActivityTaskFailed

Returns: nothing

Used by workers to tell the service that the ActivityTask identified by
the C<taskToken> has failed with C<reason> (if specified). The
C<reason> and C<details> appear in the C<ActivityTaskFailed> event
added to the workflow history.

Access Control

You can use IAM policies to control this action's access to Amazon SWF resources as follows:

Use a Resource element with the domain name to limit the action to only specified domains.
Use an Action element to allow or deny permission to call this action.
You cannot use an IAM policy to constrain this action's parameters.

RespondDecisionTaskCompleted(TaskToken => Str, [Decisions => ArrayRef[Paws::SimpleWorkflow::Decision], ExecutionContext => Str])

Each argument is described in detail in: Paws::SimpleWorkflow::RespondDecisionTaskCompleted

Returns: nothing

Used by deciders to tell the service that the DecisionTask identified
by the C<taskToken> has successfully completed. The C<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 RespondDecisionTaskCompleted, 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.

SignalWorkflowExecution(Domain => Str, SignalName => Str, WorkflowId => Str, [Input => Str, RunId => Str])

Each argument is described in detail in: Paws::SimpleWorkflow::SignalWorkflowExecution

Returns: nothing

Records a C<WorkflowExecutionSignaled> event in the workflow execution
history and creates a decision task for the workflow execution
identified by the given domain, workflowId and runId. The event is
recorded with the specified user defined signalName and input (if
provided).

If a runId is not specified, then the WorkflowExecutionSignaled event is recorded in the history of the current open workflow with the matching workflowId in the domain. If the specified workflow execution is not open, this method fails with UnknownResource.

Access Control

You can use IAM policies to control this action's access to Amazon SWF resources as follows:

Use a Resource element with the domain name to limit the action to only specified domains.

TerminateWorkflowExecution(Domain => Str, WorkflowId => Str, [ChildPolicy => Str, Details => Str, Reason => Str, RunId => Str])

Each argument is described in detail in: Paws::SimpleWorkflow::TerminateWorkflowExecution

Returns: nothing

Records a C<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.

If the identified workflow execution was in progress, it is terminated immediately. If a runId is not specified, then the WorkflowExecutionTerminated event is recorded in the history of the current open workflow with the matching workflowId in the domain. You should consider using RequestCancelWorkflowExecution action instead because it allows the workflow to gracefully close while TerminateWorkflowExecution does not.

Access Control

You can use IAM policies to control this action's access to Amazon SWF resources as follows:

Use a Resource element with the domain name to limit the action to only specified domains.
Use an Action element to allow or deny permission to call this action.
You cannot use an IAM policy to constrain this action's parameters.
