/**
 * <p>Updates the configuration of an existing state machine <a href="https://docs.aws.amazon.com/step-functions/latest/dg/concepts-state-machine-alias.html">alias</a> by modifying its <code>description</code> or <code>routingConfiguration</code>.</p>
 *          <p>You must specify at least one of the <code>description</code> or <code>routingConfiguration</code> parameters to update a state machine alias.</p>
 *          <note>
 *             <p>
 *                <code>UpdateStateMachineAlias</code> is an idempotent API. Step Functions bases the
 *         idempotency check on the <code>stateMachineAliasArn</code>, <code>description</code>, and
 *           <code>routingConfiguration</code> parameters. Requests with the same parameters return an
 *         idempotent response.</p>
 *          </note>
 *          <note>
 *             <p>This operation is eventually consistent. All <a>StartExecution</a> requests
 *         made within a few seconds use the latest alias configuration. Executions started immediately
 *         after calling <code>UpdateStateMachineAlias</code> may use the previous routing
 *         configuration.</p>
