Hi, When I ran a topology, it always created a process called "LogWriter" per worker. LogWriter seemed to write log into file when worker call "system.out.println" or "LOG.xxxx" based on configuration in log4j2. To send log info from a worker to a LogWriter, it seemed to use UDP.
Is it right? Is there a configuration to enable or disable this? Does it affect overall performance? Thanks, Junguk
