printing datastream to the log - instead of stdout

[Chen Bekor <ch...@gmail.com>]

hi,

the .print() method will print a dataset / datastream to the stdout.

how can I print the stream to the standard logger (logback/log4j)?

I'm using flink scala - so scala example code is much appreciated.

p.s - I noticed that there's a PrintFunction that I can implement but it
feels like I'm reinventing the wheel for something that should be very
elementary.

thanks!!

Chen.

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.

Best
