Kafka message counter

kafka-counter

Count kafka events from multiple topics.

This small utility reads kafka messages from multiple topics and provides you a running count of the number of seen events. If the message is a json document, you can also break down the counts for a topic by a specific key indicated by a JSON path.

When you quit the program pressing Ctrl-C, it also provides some statistics of the events seen broken down by topics.
