1. Challenge

   Clone the Starter Project from GitHub and Perform a Test Run

   1. Clone the starter project from GitHub.:

      cd ~/
      git clone https://github.com/linuxacademy/content-ccdak-producer-tuning-lab.git
      

   2. Perform a test run to make sure the code is able to compile and run:

      cd content-ccdak-producer-tuning-lab
      ./gradlew run
      

      The code should compile, and tests should succeed.

2. Challenge

   Implement the Configuration Changes in the Producer

   1. Open the file:

      props.put("max.in.flight.requests.per.connection", "1");
      

   4. Increase the batch size by setting batch.size=65536:

      props.put("batch.size", "65536");
      

   5. Run your code to verify that it still works:

      ./gradlew run
