2020/09/14 - AWS Step Functions - 6 updated api methods
Changes Update stepfunctions client to latest version
{'tracingConfiguration': {'enabled': 'boolean'}}
Creates a state machine. A state machine consists of a collection of states that can do work ( Task states), determine to which states to transition next ( Choice states), stop an execution with an error ( Fail states), and so on. State machines are specified using a JSON-based, structured language. For more information, see Amazon States Language in the AWS Step Functions User Guide.
