Example 1 with MultiReducerProcessor

use of storm.trident.planner.processor.MultiReducerProcessor in project jstorm by alibaba.

the class TridentTopology method multiReduce.

public Stream multiReduce(List<Fields> inputFields, List<Stream> streams, MultiReducer function, Fields outputFields) {
    List<String> names = new ArrayList<>();
    for (Stream s : streams) {
        if (s._name != null) {
            names.add(s._name);
        }
    }
    Node n = new ProcessorNode(getUniqueStreamId(), Utils.join(names, "-"), outputFields, outputFields, new MultiReducerProcessor(inputFields, function));
    return addSourcedNode(streams, n);
}
