Hi Chen I haven't tried the following code out but it should be as easy as:
stream.addSink(new SinkFunction<String>() { private final Logger LOG = LogManager.getLogger("loggerName"); public void invoke(String value) throws Exception { Log.info(value); } }); It's JAVA but I think it suffice to geht the basic idea. It assumes that the stream carries string entities.
