Once you import the dashboards and connect to the datasource, the kafka broker dashboard should be something like the following picture. On the other hand, storage optimized instances can get similar numbers even in non metal instances with bigger disks. If you want to test the scenario in vanilla kubernetes, I recommend kubeadm.
That is obviously not relevant in a real world scenario, but on the same reasoning is independent of the requirements for doing whatever logic on the consumer side, though we can measure right the ingestion throughput.

In order to be able to use the random data that we have created previously, we should either add it to an image, mount it as a ConfigMap binary data or use a Read-Write-Many PersistentVolumeClaim.
When we ran the load generator on a smaller AWS instance type we saw, it became a bottleneck and, as a result, Azul Platform Prime scores were lower compared to OpenJDK.
StreamNative has also produced its own benchmark report focused on comparing Apache Pulsar vs. Apache Kafka using the Linux Foundation Open Messaging benchmark.

We are defining a whole set of zookeeper and kafka brokers in a simple yaml file. With consumer tests we want to know the ability of dispatching the messages as fast as possible. Now some notes I have found on the process, and worth understanding some decisions on the way.

We measured maximum throughput by increasing the load on the server by 5000 requests per second until we reached the point at which Kafka could not reach the higher load. It is true that with redundancy at storage, we may get two redundancy levels if we use the topic replication and there is a little overhead in it. For Kafka configuration, we used the following parameters: For full instructions on running the tests and parsing output, see the benchmark GitHub page.

Today, we look at Kafka, one of the most popular event streaming platforms in the community today.
If I go for i3en.6xlarge (which is half price), I can get 24 CPUs per node, which is more than we need, and on the other hand we get the same bandwidth and significant bigger disks, 2 x 7500 NVMe SSD, so I can do longer tests.
