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.
See https://www.paws-r-sdk.com/docs/swf_poll_for_decision_task/ for full documentation.
swf_poll_for_decision_task(
domain,
taskList,
identity = NULL,
nextPageToken = NULL,
maximumPageSize = NULL,
reverseOrder = NULL,
startAtPreviousStartedEvent = NULL
)
[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 contain a :
(colon), /
(slash), |
(vertical bar), or any control characters (U+0000`-`U+001f
|
U+007f`-`U+009f
). Also, it must not be the literal string arn
.
Identity of the decider making the request, which is recorded in the DecisionTaskStarted event in the workflow history. This enables diagnostic tracing when problems arise. The form of this identity is user defined.
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
24 hours. 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.
The nextPageToken
returned by this action cannot be used with
get_workflow_execution_history
to get the next page. You must call
poll_for_decision_task
again (with the
nextPageToken
) to retrieve the next page of history records. Calling
poll_for_decision_task
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.
When set to true
, returns the events in reverse order. By default the
results are returned in ascending order of the eventTimestamp
of the
events.
When set to true
, returns the events with eventTimestamp
greater
than or equal to eventTimestamp
of the most recent
DecisionTaskStarted
event. By default, this parameter is set to
false
.
