How to push notify consumers from kafka message bus

I am writing microservice application using C# asp.net core 2.0, Kafka, CQRS and Confluent Kafka .net library.

Just wonder if kafka can notify the consumers rather than the consumers poll/consume message?

Thanks

Yes, by pushing a message onto the message bus which gets polled/consumed by the consumers. What exactly is the question or problem you have?

Kafka can not push notifications to consumers.

Consumers have to keep polling/consuming messages in order to receive them. This is the only way messages stored in Kafka can flow to consumers.

The Consumer Design section in the Apache Kafka documentation explains why "consumer pulling" was choosed over "broker pushing".
