Kafka allows you to subscribe to topics using regex, and regex pattern matching is automatically performed for topics prefixed with ^ (e.g. ^myPfx[0-9]_.*).

The consumer will see the new topics on its next periodic metadata refresh which is controlled by the topic.metadata.refresh.interval.ms

To subscribe to topics using regex, you can simply pass the regex you want to use to the subscribe method:

\Junges\Kafka\Facades\Kafka::consumer()
    ->subscribe('^myPfx_.*')
    ->withHandler(...)

This pattern will match any topics that starts with myPfx_.
