How to set consumer.id for new Kafka consumer

Question

According to the docs, Old Consumer Configs included a consumer.id set to null by default:

consumer.id
Default: null
Description: Generated automatically if not set.

Is it possible to set the consumer.id for the New Kafka Consumer and if so, how can I achieve this?

Answer 1

Kafka automatically generates a consumer.id which is used by itself to identify the active consumers in a consumer group and it is not possible to manually set the consumer.id for Kafka Consumers.
