Optional name of the execution. This name must be unique for your Amazon Web Services account, Region, and state machine for 90 days. For more information, see Limits Related to State Machine Executions in the Step Functions Developer Guide.

If you don't provide a name for the execution, Step Functions automatically generates a universally unique identifier (UUID) as the execution name.

A name must not contain:

• white space

• brackets < > { } [ ]

• wildcard characters ? *

• special characters " # % \ ^ | ~ $ & , ; : /`

• control characters (U+0000-001F, U+007F-009F)

To enable logging with CloudWatch Logs, the name should only contain 0-9, A-Z, a-z, - and _.
