Welcome to the example number three, this is probably the most important example in the entire course,
because here I'll demonstrate you how to create fault tolerant or zylon about your coffeecake.
Last, we will create Gloster with three different brokers, and afterwards we will create a topic with
multiple partitions and replication of three that is equal to quantity of service in our class.
And you'll see that every match will be copied to all brokers in our cluster.
Afterwards, we will produce Samatha just to that topic and consume them.
And next we will simulate broker failure.
It means that we will try to bring down one of the brokers and observe what will happen.
In fact, nothing will happen with producers and consumers.
They will still be up and operational.
And next, we will try to bring down one more broker and only one will remain alive.
And still our class will remain operational.
And you'll see that even with one broker alive, consumers will still be able to consume all messages
from the topic from beginning.
No messages will be lost and thus the replication.
Afterwards, we will bring back Borse brokers and get back to original state of our clasper.
Let's get started.
