Possible to have more than one streaming datasource?

[bronzels]

Dear jMetalSP commiters,

as optimization with large dataset usually takes long time, your streaming idea to add new data is brilliant to me. but my problem to resolve involves 2 kinds of data which is difficult to put into one class. as titles, any way to have more than one streaming datasource?

Of course, you can have more than one streaming datasource. You only need to add as observable the same problem. I mean, more than one streaming datasource can change the same problem, because our methods are synchronized . For example, for the TSP problem,you can add more than one streaming data source:

application.setStreamingRuntime(new SparkRuntime(10, sparkConf))
.setProblem(problem)
.setAlgorithm(algorithm)
.addStreamingDataSource(streamingTSPSource,problem)
.addStreamingDataSource(streamingTSPSource2,problem)
.addStreamingDataSource(streamingTSPSource3,problem)
.addAlgorithmDataConsumer(localDirectoryOutputConsumer)
.addAlgorithmDataConsumer(chartConsumer)
.run();
