use of org.apache.storm.trident.planner.SpoutNode in project storm by apache.

the class TridentTopology method newDRPCStream.

private Stream newDRPCStream(DRPCSpout spout) {
    // TODO: consider adding a shuffle grouping after the spout to avoid so much routing of the args/return-info all over the place
    // (at least until its possible to just pack bolt logic into the spout itself)
    Node n = new SpoutNode(getUniqueStreamId(), TridentUtils.getSingleOutputStreamFields(spout), null, spout, SpoutNode.SpoutType.DRPC);
    Stream nextStream = addNode(n);
    // later on, this will be joined back with return-info and all the results
    return nextStream.project(new Fields("args"));
