2023/11/14 - AWS Step Functions - 1 new 4 updated api methods
Changes This release adds support to redrive executions in AWS Step Functions with a new RedriveExecution operation.
Restarts unsuccessful executions of Standard workflows that didn't complete successfully in the last 14 days. These include failed, aborted, or timed out executions. When you redrive an execution, it continues the failed execution from the unsuccessful step and uses the same input. Step Functions preserves the results and execution history of the successful steps, and doesn't rerun these steps when you redrive an execution. Redriven executions use the same state machine definition and execution ARN as the original execution attempt.
For workflows that include an Inline Map or Parallel state, RedriveExecution API action reschedules and redrives only the iterations and branches that failed or aborted.
To redrive a workflow that includes a Distributed Map state with failed child workflow executions, you must redrive the parent workflow . The parent workflow redrives all the unsuccessful states, including Distributed Map.
Note
This API action is not supported by EXPRESS state machines.
However, you can restart the unsuccessful executions of Express child workflows in a Distributed Map by redriving its Map Run. When you redrive a Map Run, the Express child workflows are rerun using the StartExecution API action. For more information, see Redriving Map Runs .
You can redrive executions if your original execution meets the following conditions:
The execution status isn't SUCCEEDED .
Your workflow execution has not exceeded the redrivable period of 14 days. Redrivable period refers to the time during which you can redrive a given execution. This period starts from the day a state machine completes its execution.
The workflow execution has not exceeded the maximum open time of one year. For more information about state machine quotas, see Quotas related to state machine executions .
The execution event history count is less than 24,999. Redriven executions append their event history to the existing event history. Make sure your workflow execution contains less than 24,999 events to accommodate the ExecutionRedriven history event and at least one other history event.

Request Syntax
client.redrive_execution(
executionArn='string',
clientToken='string'
)
string
[REQUIRED]
The Amazon Resource Name (ARN) of the execution to be redriven.
string
A unique, case-sensitive identifier that you provide to ensure the idempotency of the request. If you don’t specify a client token, the Amazon Web Services SDK automatically generates a client token and uses it for the request to ensure idempotency. The API uses one of the last 10 client tokens provided.
This field is autopopulated if not provided.

Provides information about a state machine execution, such as the state machine associated with the execution, the execution input and output, and relevant execution metadata. If you've redriven an execution, you can use this API action to return information about the redrives of that execution. In addition, you can use this API action to return the Map Run Amazon Resource Name (ARN) if the execution was dispatched by a Map Run.
If you specify a version or alias ARN when you call the StartExecution API action, DescribeExecution returns that ARN.
Note
This operation is eventually consistent. The results are best effort and may not reflect very recent updates and changes.
Executions of an EXPRESS state machine aren't supported by DescribeExecution unless a Map Run dispatched them.

Provides details about execution input or output.
included (boolean) --
Indicates whether input or output was included in the response. Always true for API calls.
output (string) --
The JSON output data of the execution. Length constraints apply to the payload size, and are expressed as bytes in UTF-8 encoding.
Note
This field is set only if the execution succeeds. If the execution fails, this field is null.

stateMachineVersionArn (string) --
The Amazon Resource Name (ARN) of the state machine version associated with the execution. The version ARN is a combination of state machine ARN and the version number separated by a colon (:). For example, stateMachineARN:1 .
If you start an execution from a StartExecution request without specifying a state machine version or alias ARN, Step Functions returns a null value.
stateMachineAliasArn (string) --
The Amazon Resource Name (ARN) of the state machine alias associated with the execution. The alias ARN is a combination of state machine ARN and the alias name separated by a colon (:). For example, stateMachineARN:PROD .
If you start an execution from a StartExecution request with a state machine version ARN, this field will be null.
redriveCount (integer) --

The date the execution was last redriven. If you have not yet redriven an execution, the redriveDate is null.
The redriveDate is unavailable if you redrive a Map Run that starts child workflow executions of type EXPRESS .
redriveStatus (string) --
Indicates whether or not an execution can be redriven at a given point in time.
For executions of type STANDARD , redriveStatus is NOT_REDRIVABLE if calling the RedriveExecution API action would return the ExecutionNotRedrivable error.
For a Distributed Map that includes child workflows of type STANDARD , redriveStatus indicates whether or not the Map Run can redrive child workflow executions.
For a Distributed Map that includes child workflows of type EXPRESS , redriveStatus indicates whether or not the Map Run can redrive child workflow executions. You can redrive failed or timed out EXPRESS workflows only if they're a part of a Map Run. When you redrive the Map Run, these workflows are restarted using the StartExecution API action.
redriveStatusReason (string) --
When redriveStatus is NOT_REDRIVABLE , redriveStatusReason specifies the reason why an execution cannot be redriven.
For executions of type STANDARD , or for a Distributed Map that includes child workflows of type STANDARD , redriveStatusReason can include one of the following reasons:
State machine is in DELETING status .
Execution is RUNNING and cannot be redriven .
Execution is SUCCEEDED and cannot be redriven .
Execution was started before the launch of RedriveExecution .
Execution history event limit exceeded .
Execution has exceeded the max execution time .
Execution redrivable period exceeded .
For a Distributed Map that includes child workflows of type EXPRESS , redriveStatusReason is only returned if the child workflows are not redrivable. This happens when the child workflow executions have completed successfully.

Response {'executions': {'redriveCount': 'integer',
'redriveDate': 'timestamp',
'status': {'PENDING_REDRIVE'}}}
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. Using this API action, you can also list all redriven executions.
You can also provide a state machine alias ARN or version ARN to list the executions associated with a specific alias or version.
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.
Note
This operation is eventually consistent. The results are best effort and may not reflect very recent updates and changes.
This API action is not supported by EXPRESS state machines.

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.
You can also return a list of executions associated with a specific alias or version , by specifying an alias ARN or a version ARN in the stateMachineArn parameter.
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.
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.
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.
string
Sets a filter to list executions based on whether or not they have been redriven.
For a Distributed Map, redriveFilter sets a filter to list child workflow executions based on whether or not they have been redriven.
If you do not provide a redriveFilter , Step Functions returns a list of both redriven and non-redriven executions.
If you provide a state machine ARN in redriveFilter , the API returns a validation exception.
