Update State Machine

sfn_update_state_machine

R Documentation

Updates an existing state machine by modifying its definition, roleArn, loggingConfiguration, or EncryptionConfiguration

Description

Updates an existing state machine by modifying its definition, roleArn, loggingConfiguration, or EncryptionConfiguration. Running executions will continue to use the previous definition and roleArn. You must include at least one of definition or roleArn or you will receive a MissingRequiredParameter error.

A qualified state machine ARN refers to a Distributed Map state defined within a state machine. For example, the qualified state machine ARN arn:partition:states:region:account-id:stateMachine:stateMachineName/mapStateLabel refers to a Distributed Map state with a label mapStateLabel in the state machine named stateMachineName.

A qualified state machine ARN can either refer to a Distributed Map state defined within a state machine, a version ARN, or an alias ARN.

The following are some examples of qualified and unqualified state machine ARNs:

• The following qualified state machine ARN refers to a Distributed Map state with a label mapStateLabel in a state machine named myStateMachine.

  arn:partition:states:region:account-id:stateMachine:myStateMachine/mapStateLabel

  If you provide a qualified state machine ARN that refers to a Distributed Map state, the request fails with ValidationException.

• The following qualified state machine ARN refers to an alias named PROD.

  ⁠arn:<partition>:states:<region>:<account-id>:stateMachine:<myStateMachine:PROD>⁠

  If you provide a qualified state machine ARN that refers to a version ARN or an alias ARN, the request starts execution for that version or alias.

• The following unqualified state machine ARN refers to a state machine named myStateMachine.

  ⁠arn:<partition>:states:<region>:<account-id>:stateMachine:<myStateMachine>⁠

After you update your state machine, you can set the publish parameter to true in the same action to publish a new version. This way, you can opt-in to strict versioning of your state machine.

Step Functions assigns monotonically increasing integers for state machine versions, starting at version number 1.

All start_execution calls within a few seconds use the updated definition and roleArn. Executions started immediately after you call update_state_machine may use the previous state machine definition and roleArn.

Usage

sfn_update_state_machine(stateMachineArn, definition, roleArn,
  loggingConfiguration, tracingConfiguration, publish, versionDescription,
  encryptionConfiguration)

Arguments

stateMachineArn	[required] The Amazon Resource Name (ARN) of the state machine.
definition	The Amazon States Language definition of the state machine. See Amazon States Language.
roleArn	The Amazon Resource Name (ARN) of the IAM role of the state machine.
loggingConfiguration	Use the LoggingConfiguration data type to set CloudWatch Logs options.
tracingConfiguration	Selects whether X-Ray tracing is enabled.
publish	Specifies whether the state machine version is published. The default is false. To publish a version after updating the state machine, set publish to true.
versionDescription	An optional description of the state machine version to publish. You can only specify the versionDescription parameter if you've set publish to true.
encryptionConfiguration	Settings to configure server-side encryption.
