             Summary: KafkaConsumer.subscribe() override that takes just 
Pattern without ConsumerRebalanceListener
                 Key: KAFKA-5726
             Project: Kafka
          Issue Type: Improvement
          Components: consumer
    Affects Versions:
            Reporter: Yeva Byzek
            Priority: Minor

Request: provide {{subscribe(Pattern pattern)}} override, similar to 
{{subscribe(Collection<String> topics)}}, 

Today, for a consumer to subscribe to topics based on a regular expression 
(i.e. {{Pattern}}), the only method option also requires to pass in a 
{{ConsumerRebalanceListener}}. This is not user-friendly to require this second 
argument. It seems {{new NoOpConsumerRebalanceListener()}} has to be used.  

Use case: multi datacenter, allowing easier subscription to multiple topics 
prefixed with datacenter names, just by using a pattern subscription.
