Multiple sinks cannot be implemented

StreamBuilder builder = new StreamBuilder("wordCount");

RStream source = builder.source("stream-topic-1", total -> {
String value = new String(total, StandardCharsets.UTF_8);
JSONObject jsonObject = JSON.parseObject(value);
return new Pair<>(null, jsonObject);
});

source.print();
source.sink("stream-topic-sink",new KVJsonSerializer<>());

TopologyBuilder topologyBuilder = builder.build();

In TopologyBuilder, public Processor build(String topicName) is executed in node order and cannot implement multiple sinks. The above code can only execute the first sink.
