+ * A simple example that shows how to read from and write to Kafka. This will
read String messages
+ * from the input topic, parse them into a POJO type {@link KafkaEvent}, group
by some key, and finally
+ * perform a rolling addition on each key for which the results are written
back to another topic.
+ *
+ * <p>This example also demonstrates using a watermark assigner to generate
per-partition
+ * watermarks directly in the Flink Kafka consumer. For demonstration
purposes, it is assumed that
+ * the String messages are of formatted as a (word,frequency,timestamp) tuple.
+ *
+ * <p>Example usage:
+ * --input-topic test-input --output-topic test-output --bootstrap.servers
localhost:9092 --zookeeper.connect localhost:2181 --group.id myconsumer
