             Summary: 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


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-*
      valueType: blah
      targets:
          - blah{code}
The Flink consumer can be configured with both a list of concrete topics + a pattern so validation is simple.
