can you please tell me use case of Kafka & schema registry of kakfa in datahub, what kind of data , kafka stored?

hey Nischay! So Kafka is used as an event streaming service where we stream different changes to metadata on the platform. It allows us to communicate changes to the different pieces of the platform architecture and it allows you to subscribe to different changes in metadata. For specifics on what is actually being streamed and what the different types of metadata changes are, I would check out the docs around Metadata Events: https://datahubproject.io/docs/what/mxe
