Dmitry Minaev commented on BEAM-5786:
-------------------------------------
We definitely need to be able to discover new topics at runtime. But since it's
a major change maybe it'll be good to at least resolve it at the start for now
and then work on the bigger change.
> 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
> Assignee: Alexey Romanenko
> Priority: Major
>
> 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.
