Usage

Source

ParameterTool parameterTool = ParameterTool.fromArgs(args);

StreamExecutionEnvironment env = StreamExecutionEnvironment.createLocalEnvironment();

Topic<_String> stringTopic =
    defaultDomainParticipant().createTopic("FlinkExample", _String.class);

DataStream<_String> dataStream =
    env.addSource(new FlinkVortexReader<>(stringTopic, parameterTool.getProperties()));

dataStream.print();

env.execute("DDS source example.");

Sink

ParameterTool parameterTool = ParameterTool.fromArgs(args);

StreamExecutionEnvironment env = StreamExecutionEnvironment.createLocalEnvironment();

Topic<_String> stringTopic =
    defaultDomainParticipant().createTopic("FlinkExample", _String.class);

DataStream<_String> dataStream;

// do something with the data stream

dataStream.addSink(new FlinkVortexWriter<_String>(stringTopic, parameterTool.getProperties()));

env.execute("DDS sink example");
