So Kafka is very efficient because it takes bytes as an input and then publishes them to consumers. Okay. So there is no data verification done. Your producer is just produces a series of zeros and ones and then your consumers read these zeros and ones. And then the producer to produce the zeros and ones, they will use a serializer and the consumer to consume them, they will use a deserializer. But what if the producer starts sending bad data, for example, a different format? Or what if it feels get renamed? What if the data format changes from one date to another? Then all consumers will break because they are not aware of this. They expect a specific deserializer and then they will crash at runtime because while the deserializer is failing. That means you need a schema registry. We need data to be self describable. We want to be able to evolve data over time…
