Get Job Stats API

A GetJobsStatsRequest object can have any number of jobId entries. However, they all must be non-null. An empty list is the same as requesting statistics for all jobs.

GetJobStatsRequest request = new GetJobStatsRequest("get-machine-learning-job-stats1", "get-machine-learning-job-*"); 
request.setAllowNoJobs(true); 

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

GetJobStatsResponse response = client.machineLearning().getJobStats(request, RequestOptions.DEFAULT);

Executing a GetJobStatsRequest 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 get-job-stats method:

client.machineLearning().getJobStatsAsync(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.

A typical listener for get-job-stats looks like:

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

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

The returned GetJobStatsResponse contains the requested job statistics:

long numberOfJobStats = response.count(); 
List<JobStats> jobStats = response.jobStats();
