> KafkaIO should support topic patterns
> -------------------------------------
>
> Key: BEAM-5786
> URL: https://issues.apache.org/jira/browse/BEAM-5786
> Project: Beam
> Issue Type: Improvement
> Components: io-java-kafka
> Reporter: Alexey Romanenko
> Priority: P3
>
> For the moment, it is possible to set topics for KafkaIO.Read in 2 ways - one
> single topic by using {{withTopic(String)}} or list of topics by using
> {{withTopics(List<String>)}}.
> It would make sense to provide another way for this using patterns, based on
> regular expressions, like {{withTopics(“org_[0-9]+_source”)}}. In this case,
> Kafka consumer could discover the topics based on user provided pattern.
