But Kafka does significantly more.

And if your needs are simpler like in this case then there are dozens of smaller pub/sub/queue systems that you could compare this to.

Limit the types of server used to reduce system complexity. If you can have all your business state in the same place, ops are much easier.

Kafka does more for streaming data, but doesn't do squat for relational data. You always need a database, but you sometimes can get by without a queuing system.

Briefly what are some mandatory kafka use cases?

>>threes+(OP)
I would say postgres does much more. What use case can only Kafka handle?
