Support multiple topic pattern in KafkaListener

[rajjaiswalsaumya]

Do we support multiple topicpattern in KafkaListener ? I see topicPattern is String while the topics is String array. Unfortunately, in our case, topics are created by customers so microservice does not know the topic name beforehand. So we use a pattern for customer topic creation in kafka but the same listener does not listen to the topics as topics does not support a pattern and requires an exact topic name while topicpattern accepts a single topic pattern.

Yes, but the pattern is a Regular Expression (RegEx) so you can use (foo.*|bar.*) or similar to match multiple patterns.

Also, this is a limitation of the underlying kafka-clients API, which only takes a single pattern.
