      <append>true</append>
      <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
         <fileNamePattern>${log.file}.%d{yyyy-MM-dd}.%i</fileNamePattern>

   <logger name="org.apache.flink" level="INFO"/>

   <!-- The following lines keep the log level of common libraries/connectors on
       log level INFO. The root logger does not override this. You have to manually
       change the log levels here. -->
   <logger name="akka" level="INFO"/>
   <logger name="org.apache.kafka" level="INFO"/>
   <logger name="org.apache.hadoop" level="INFO"/>
