Hi,

In Kafka consumer has to pool for new messages and if new message is found Kafka returns it to the consumer.

There is no way to pushing messages to subscriber in Kafka. This is implemented in this way to improve the performance of the system. Client can pool for messages at any time and Kafka server will return the messages.

Push message from Kafka server to client is not implemented in Kafka because if there are many message and server push it to client, in that case client may not have enough bandwidth to process all these messages.

Kafka waits for the message retrieval requests from client and on request it servers the messages.

Check more tutorials: Apache Kafka Tutorials

Thanks
