- Defined in:
- (unknown)
Overview
An API client for Amazon Simple Workflow Service. To construct a client, you need to configure a :region
and :credentials
.
swf = Aws::SWF::Client.new(
region: region_name,
credentials: credentials,
# ...
)
See #initialize for a full list of supported configuration options.
Region
You can configure a default region in the following locations:
ENV['AWS_REGION']
Aws.config[:region]
Go here for a list of supported regions.
Credentials
Default credentials are loaded automatically from the following locations:
ENV['AWS_ACCESS_KEY_ID']
andENV['AWS_SECRET_ACCESS_KEY']
Aws.config[:credentials]
- The shared credentials ini file at
~/.aws/credentials
(more information) - From an instance profile when running on EC2
You can also construct a credentials object from one of the following classes:
Alternatively, you configure credentials with :access_key_id
and
:secret_access_key
:
# load credentials from disk
creds = YAML.load(File.read('/path/to/secrets'))
Aws::SWF::Client.new(
access_key_id: creds['access_key_id'],
secret_access_key: creds['secret_access_key']
)
Always load your credentials from outside your application. Avoid configuring credentials statically and never commit them to source control.

#poll_for_activity_task(options = {}) ⇒ Types::ActivityTask
Used by workers to get an ActivityTask from the specified activity 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 returns 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

Constrain the
taskList.name
parameter by using aCondition
element with theswf:taskList.name
key to allow the action to access only certain task lists.
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.
#poll_for_decision_task(options = {}) ⇒ Types::DecisionTask
Used by deciders to get a DecisionTask from the specified decision 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.

taskList.name
parameter by using aCondition
element with theswf:taskList.name

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.
#record_activity_task_heartbeat(options = {}) ⇒ Types::ActivityTaskStatus
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.
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. -

#request_cancel_workflow_execution(options = {}) ⇒ Struct
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.
If the runId isn't specified, the Because this action allows the workflow to properly clean up and gracefully close, it should be used instead of TerminateWorkflowExecution when possible.WorkflowExecutionCancelRequested
event is recorded in the history of the current open workflow execution with the specified workflowId in the domain.

#respond_activity_task_canceled(options = {}) ⇒ Struct
Used by workers to tell the service that the ActivityTask identified by the taskToken
was successfully canceled. Additional details
can be provided using the 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:

#respond_activity_task_completed(options = {}) ⇒ Struct
Used by workers to tell the service that the ActivityTask identified by the taskToken
completed successfully with a result
(if provided). The result
appears in the ActivityTaskCompleted
event in the workflow history.
If the requested task doesn't 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.
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.

#respond_activity_task_failed(options = {}) ⇒ Struct
Used by workers to tell the service that the ActivityTask identified by the taskToken
has failed with reason
(if specified). The reason
and details
appear in the ActivityTaskFailed
event added to the workflow history.
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.

#respond_decision_task_completed(options = {}) ⇒ Struct
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 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 in the Amazon SWF Developer Guide.
#signal_workflow_execution(options = {}) ⇒ Struct
Records a 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).

#untag_resource(options = {}) ⇒ Struct
Remove a tag from a Amazon SWF domain.
#wait_until(waiter_name, params = {}) {|waiter| ... } ⇒ Boolean
Waiters polls an API operation until a resource enters a desired state.
Basic Usage
Waiters will poll until they are succesful, they fail by entering a terminal state, or until a maximum number of attempts are made.
# polls in a loop, sleeping between attempts client.waiter_until(waiter_name, params)
Configuration
You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. You configure waiters by passing a block to #wait_until:
# poll for ~25 seconds
client.wait_until(...) do |w|
w.max_attempts = 5
w.delay = 5
end
Callbacks
You can be notified before each polling attempt and before each
delay. If you throw :success
or :failure
from these callbacks,
it will terminate the waiter.
started_at = Time.now
client.wait_until(...) do |w|
# disable max attempts
w.max_attempts = nil
# poll for 1 hour, instead of a number of attempts
w.before_wait do |attempts, response|
throw :failure if Time.now - started_at > 3600
end
end
Handling Errors
When a waiter is successful, it returns true
. When a waiter
fails, it raises an error. All errors raised extend from
Waiters::Errors::WaiterFailed.
begin
client.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
# resource did not enter the desired state in time
end
#waiter_names ⇒ Array<Symbol>
Returns the list of supported waiters. The following table lists the supported waiters and the client method they call:
Waiter Name | Client Method | Default Delay: | Default Max Attempts: |
---|
