Hi Karan, Yeah, so as to Paolo's point, keep in mind that Kafka does not guarantee order across partitions, only within a partition. If you publish messages to a topic with 3 partitions, it will only be guaranteed that they are consumed in order within the partition.
You can retry your test by publishing to a single partition topic. When you consume, you should see that it is all in order. I hope that helps.
