> Allow regex subscriptions in the new consumer
> ---------------------------------------------
>
> Key: KAFKA-1893
> URL: https://issues.apache.org/jira/browse/KAFKA-1893
> Project: Kafka
> Issue Type: Sub-task
> Components: consumer
> Reporter: Jay Kreps
> Assignee: Ashish K Singh
> Priority: Blocker
> Fix For: 0.8.3
>
>
> The consumer needs to handle subscribing to regular expressions. Presumably
> this would be done as a new api,
> {code}
> void subscribe(java.util.regex.Pattern pattern);
> {code}
> Some questions/thoughts to work out:
> - It should not be possible to mix pattern subscription with partition
> subscription.
> - Is it allowable to mix this with normal topic subscriptions? Logically
> this is okay but a bit complex to implement.
> - We need to ensure we regularly update the metadata and recheck our regexes
> against the metadata to update subscriptions for new topics that are created
> or old topics that are deleted.
