This directory contains examples of client code that uses kafka.

To run the demo: 

   1. Start Zookeeper and the Kafka server
   2. For simple consumer demo, `run bin/java-simple-consumer-demo.sh`
   3. For unlimited sync-producer-consumer run, `run bin/java-producer-consumer-demo.sh sync`
   4. For unlimited async-producer-consumer run, `run bin/java-producer-consumer-demo.sh`
   5. For exactly once demo run, `run bin/exactly-once-demo.sh 6 3 50000`,
      this means we are starting 3 EOS instances with 6 topic partitions and 50000 pre-populated records.
   6. Some notes for exactly once demo:
      6.1. The Kafka server has to be on broker version 2.5 or higher.
      6.2. You could also use Intellij to run the example directly by configuring parameters as "Program arguments"
