| <note>Before running this pipeline, make sure a kafka server is running with two topics: hop-in and hop-out. | ||
| Example run of producer: | ||
| # bin/kafka-console-producer.sh --topic hop-in --bootstrap-server localhost:9092 --property "parse.key=true" --property "key.separator=:" | ||
|
|
||
| produce messages into in-topic in json format (e.g. {"name":"toni"}), the pipeline counts the number of times each name is shown | ||
