--------------------------------------
Hi [~sjwiesman],
Just commenting here to keep track of the status of this feature:
We discussed this feature offline with [~tzulitai] and concluded that we would
like to iterate on the design one more time, and try to make it happen for 3.1
release.
> Support Kafka Topic Patterns in Kafka Ingress
> ---------------------------------------------
>
> Key: FLINK-22554
> URL: https://issues.apache.org/jira/browse/FLINK-22554
> Project: Flink
> Issue Type: Improvement
> Components: Stateful Functions
> Affects Versions: statefun-3.1.0
> Reporter: Seth Wiesman
> Assignee: Seth Wiesman
> Priority: Major
> Labels: pull-request-available
> Fix For: statefun-3.1.0
>
>
> Flink's Kafka source supports subscription patterns, where it will consume
> all topics that match a specified regex and periodically monitor for new
> topics. We should support this in the statefun Kafka ingress as it is
> generally useful and would remove a source of cluster downtime (subscribing
> to a new topic).
>
> I propose something like this.
>
> {code:java}
> topics:
> - topic-pattern: my-topic-* // some regex
> discovery-interval: 10s // some duration
> valueType: blah
> targets:
> - blah{code}
> The Flink consumer can be configured with both a list of concrete topics + a
> pattern so validation is simple.
