swf_list_open_workflow_executions: Returns a list of open workflow executions in the specified domain that meet the filtering criteria

Description

Returns a list of open workflow executions in the specified domain that meet the filtering criteria. The results may be split into multiple pages. To retrieve subsequent pages, make the call again using the nextPageToken returned by the initial call.

Usage

swf_list_open_workflow_executions(domain, startTimeFilter, typeFilter,
  tagFilter, nextPageToken, maximumPageSize, reverseOrder,
  executionFilter)

Arguments

domain

[required] The name of the domain that contains the workflow executions to list.

startTimeFilter

[required] Workflow executions are included in the returned results based on whether their start times are within the range specified by this filter.

typeFilter

If specified, only executions of the type specified in the filter are returned.

executionFilter, typeFilter and tagFilter are mutually exclusive. You can specify at most one of these in a request.

tagFilter

If specified, only executions that have the matching tag are listed.

executionFilter, typeFilter and tagFilter are mutually exclusive. You can specify at most one of these in a request.

nextPageToken

If a NextPageToken was returned by a previous call, there are more results available. To retrieve the next page of results, make the call again using the returned token in nextPageToken. Keep all other arguments unchanged.

The configured maximumPageSize determines how many results can be returned in a single call.

maximumPageSize

The maximum number of results that are returned per call. nextPageToken can be used to obtain futher pages of results. The default is 1000, which is the maximum allowed page size. You can, however, specify a page size smaller than the maximum.

This is an upper limit only; the actual number of results returned per call may be fewer than the specified maximum.

reverseOrder

When set to true, returns the results in reverse order. By default the results are returned in descending order of the start time of the executions.

executionFilter

If specified, only workflow executions matching the workflow ID specified in the filter are returned.

executionFilter, typeFilter and tagFilter are mutually exclusive. You can specify at most one of these in a request.

Request syntax

svc$list_open_workflow_executions(
  domain = "string",
  startTimeFilter = list(
    oldestDate = as.POSIXct(
      "2015-01-01"
    ),
    latestDate = as.POSIXct(
      "2015-01-01"
    )
  ),
  typeFilter = list(
    name = "string",
    version = "string"
  ),
  tagFilter = list(
    tag = "string"
  ),
  nextPageToken = "string",
  maximumPageSize = 123,
  reverseOrder = TRUE|FALSE,
  executionFilter = list(
    workflowId = "string"
  )
)

Details

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 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.
