From another terminal, run the following command to run the consumer application which will read the events from the purchases topic and write the information to the terminal.
The consumer application will start and print any events it has not yet consumed and then wait for more events to arrive. On startup of the consumer, you should see output resembling this:
Consumed event from topic purchases: key = jsmith value = gift card
Consumed event from topic purchases: key = awalther value = batteries
Consumed event from topic purchases: key = awalther value = gift card
Consumed event from topic purchases: key = awalther value = book
Consumed event from topic purchases: key = htanaka value = book
Consumed event from topic purchases: key = sgarcia value = gift card
Consumed event from topic purchases: key = sgarcia value = t-shirts
Consumed event from topic purchases: key = sgarcia value = gift card
Consumed event from topic purchases: key = sgarcia value = book
Consumed event from topic purchases: key = sgarcia value = gift card
Rerun the producer to see more events, or feel free to modify the code as necessary to create more or different events.
Once you are done, enter Ctrl-C to terminate the consumer application.
