   @savearray2 
   Thank you for your contribution.
   
   Could you change the interface like other pulsar client libraries?
   ```
   const consumer = await client.subscribe({
     topicsPattern: 'persistent://public/default/produce-abc[a-z]ef',
   });
   ```
   
   golang
   http://pulsar.apache.org/docs/en/client-libraries-go/#receive-example
   ```
   topicsPattern := fmt.Sprintf("persistent://%s/foo.*", namespace)
   opts := ConsumerOptions{
       TopicsPattern:    topicsPattern,
       SubscriptionName: "regex-sub",
   }
   ```
   
   java
   
http://pulsar.apache.org/docs/en/client-libraries-java/#multi-topic-subscriptions
   ```
   Pattern allTopicsInNamespace = 
Pattern.compile("persistent://public/default/.*");
   Consumer allTopicsConsumer = consumerBuilder
           .topicsPattern(allTopicsInNamespace)
           .subscribe();
