00:04.420 --> 00:10.990
In the next example, let's again start last hour with three different disavowals, and we will use

00:10.990 --> 00:15.700
the same set of configuration files that we have created in a previous example.

00:16.060 --> 00:19.090
And afterwards we will create the new topic.

00:19.090 --> 00:26.920
But now with replication of three, remember that in a previous example, we have created topic with

00:26.920 --> 00:29.830
file partitions, but with replication of fact or one.

00:30.070 --> 00:36.220
And afterwards we have tried to bring down one of the brokers and we have seen that the part of the

00:36.220 --> 00:41.710
math just, well, simply lost nothing because we didn't use any replication and messages.

00:41.920 --> 00:47.030
Each copy of the message where are stored just on a single breuker.

00:47.290 --> 00:53.830
So that's why in this example as to why with replication and see what will happen if we will bring one

00:53.830 --> 00:55.560
of the brokers down afterwards.

00:55.960 --> 01:03.070
But before starting with that example, let's quickly clean up our setup after previous example.

01:03.220 --> 01:08.400
And the important is that in DMP folder you need to remove Kafka.

01:08.420 --> 01:16.200
This logs folders that were created by area of the broadcast and for that, just to use around Araf

01:16.840 --> 01:26.620
golf looks this zero like so this one and this two and lets around RF Zookeeper folder like Soul and

01:26.740 --> 01:28.960
also in the user directory.

01:28.960 --> 01:36.010
I have removed old Kafka folder and placed here Nukaga folder with the clean installation of files and

01:36.010 --> 01:41.080
noticed that in a config folder there are no custom Saradha properties files.

01:41.080 --> 01:48.130
But in this example we need those files and I have actually prepared them for you and they are available

01:48.280 --> 01:50.710
at GitHub Repository and all.

01:50.710 --> 01:57.290
What we need to do now is to take those files from there and paste here into config folder.

01:57.490 --> 01:59.920
So let me go to repository.

02:00.070 --> 02:07.340
In my case, I have garlanded the two desktop and Hegal two examples and find folder with title zero

02:07.340 --> 02:10.230
or three multiple brokers and or application.

02:10.540 --> 02:17.140
Go into this folder, go to config folder and take those three files for every Aldeburgh across.

02:17.440 --> 02:25.060
Simply copied them, go afterwards into config folder of your Kafka installation and paste those files

02:25.060 --> 02:26.020
here like Seoul.

02:26.320 --> 02:32.980
And now I have three custom built properties files for each of the brokers that we will start in this

02:32.980 --> 02:33.580
example.

02:33.940 --> 02:38.950
So that's basically all what you need to do in order to start with this example and let's start with

02:38.950 --> 02:41.130
it in the next season by bye.
