A StopDataFrameTransformRequest object requires a non-null id. id can be a comma separated list of IDs or a single ID. Wildcards, * and _all are also accepted.

StopDataFrameTransformRequest request =
        new StopDataFrameTransformRequest("mega-transform"); 

The following arguments are optional.

request.setWaitForCompletion(Boolean.TRUE);  
request.setTimeout(TimeValue.timeValueSeconds(30));  
request.setAllowNoMatch(true); 

When executing a StopDataFrameTransformRequest in the following manner, the client waits for the StopDataFrameTransformResponse to be returned before continuing with code execution:

StopDataFrameTransformResponse response =
        client.dataFrame().stopDataFrameTransform(
                request, RequestOptions.DEFAULT);

Synchronous calls may throw an IOException in case of either failing to parse the REST response in the high-level REST client, the request times out or similar cases where there is no response coming back from the server.

In cases where the server returns a 4xx or 5xx error code, the high-level client tries to parse the response body error details instead and then throws a generic ElasticsearchException and adds the original ResponseException as a suppressed exception to it.

Executing a StopDataFrameTransformRequest can also be done in an asynchronous fashion so that the client can return directly. Users need to specify how the response or potential failures will be handled by passing the request and a listener to the asynchronous stop-transform method:

client.dataFrame().stopDataFrameTransformAsync(
        request, RequestOptions.DEFAULT, listener); 

The asynchronous method does not block and returns immediately. Once it is completed the ActionListener is called back using the onResponse method if the execution successfully completed or using the onFailure method if it failed. Failure scenarios and expected exceptions are the same as in the synchronous execution case.

A typical listener for stop-transform looks like:

ActionListener<StopDataFrameTransformResponse> listener =
        new ActionListener<StopDataFrameTransformResponse>() {
            @Override
            public void onResponse(
                    StopDataFrameTransformResponse response) {
                
            }

            @Override
            public void onFailure(Exception e) {
                
            }
        };

The returned StopDataFrameTransformResponse object acknowledges the transform has stopped.
