Andres Gomez Ferrer commented on KAFKA-4633:
--------------------------------------------
[~mjsax] ok!! I understand, so I will use auto-repartitioning. Thanks a lot for
the explanation.
> Always use regex pattern subscription to avoid auto create topics

> Key: KAFKA-4633
> URL: https://issues.apache.org/jira/browse/KAFKA-4633
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Reporter: Guozhang Wang
> Assignee: Guozhang Wang
> Labels: architecture
> Fix For: 0.10.2.0
>
>
> In {{KafkaConsumer}}, a metadata update is requested whenever
> {{subscribe(List<String> topics ..)}} is called. And when such a metadata
> request is sent to the broker upon the first {{poll}} call, it will cause the
> broker to auto-create any topics that do not exist if the broker-side config
> {{topic.auto.create}} is turned on.
> In order to work around this issue until the config is default to false and
> gradually be deprecated, we will let Streams to always use the other
> {{subscribe}} function with regex pattern, which will send the metadata
> request with empty topic list and hence won't trigger broker-side auto topic
> creation.
> The side-effect is that the metadata response will be larger, since it
> contains all the topic infos; but since we only refresh it infrequently this
> will add negligible overhead.
