Seth Wiesman updated FLINK-22554:
---------------------------------
Description:
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.
