the class DefaultXmlAsyncClient method eventStreamOperation.
/**
* Invokes the EventStreamOperation operation asynchronously.

* @param eventStreamOperationRequest
* @return A Java Future containing the result of the EventStreamOperation operation returned by the service.<br/>
* The CompletableFuture returned by this method can be completed exceptionally with the following
* exceptions.
* <ul>
* <li>SdkException Base class for all exceptions that can be thrown by the SDK (both service and client).
* Can be used for catch all scenarios.</li>
* <li>SdkClientException If any client side error occurs such as an IO related failure, failure to get
* credentials, etc.</li>
* <li>XmlException Base class for all service exceptions. Unknown exceptions will be thrown as an instance
* of this type.</li>
