2022/12/01 - AWS Step Functions - 3 new5 updated api methods
Changes Update stepfunctions client to latest version
Lists all Map Runs that were started by a given state machine execution. Use this API action to obtain Map Run ARNs, and then call DescribeMapRun to obtain more information, if needed.

Request Syntax
client.list_map_runs(
executionArn='string',
maxResults=123,
nextToken='string'
)
string
[REQUIRED]
The Amazon Resource Name (ARN) of the execution for which the Map Runs must be listed.
integer
The maximum number of results that are returned per call. You can use nextToken to obtain further pages of results. The default is 100 and the maximum allowed page size is 1000. A value of 0 uses the default.
This is only an upper limit. The actual number of results returned per call might be fewer than the specified maximum.
string
If nextToken is returned, there are more results available. The value of nextToken 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 an HTTP 400 InvalidToken error.

{'mapRunArn': 'string'}
Response {'executions': {'itemCount': 'integer', 'mapRunArn': 'string'}}
Lists all executions of a state machine or a Map Run. You can list all executions related to a state machine by specifying a state machine Amazon Resource Name (ARN), or those related to a Map Run by specifying a Map Run ARN.
Results are sorted by time, with the most recent execution first.
If nextToken is returned, there are more results available. The value of nextToken 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 an HTTP 400 InvalidToken error.
This API action is not supported by EXPRESS state machines.

stateMachineArn='string',
statusFilter='RUNNING'|'SUCCEEDED'|'FAILED'|'TIMED_OUT'|'ABORTED',
maxResults=123,
nextToken='string',
mapRunArn='string'
)
string
The Amazon Resource Name (ARN) of the state machine whose executions is listed.
You can specify either a mapRunArn or a stateMachineArn, but not both.
string
If specified, only list the executions whose current execution status matches the given filter.
integer
The maximum number of results that are returned per call. You can use nextToken to obtain further pages of results. The default is 100 and the maximum allowed page size is 1000. A value of 0 uses the default.
This is only an upper limit. The actual number of results returned per call might be fewer than the specified maximum.

If nextToken is returned, there are more results available. The value of nextToken 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 an HTTP 400 InvalidToken error.
string
The Amazon Resource Name (ARN) of the Map Run that started the child workflow executions. If the mapRunArn field is specified, a list of all of the child workflow executions started by a Map Run is returned. For more information, see Examining Map Run in the Step Functions Developer Guide.
You can specify either a mapRunArn or a stateMachineArn, but not both.
