### Search before asking - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar. ### What issue do you find in Pulsar docs? I think it would be useful to introduce the ReaderListener in the [Reader interface introduction](https://pulsar.apache.org/docs/2.11.x/concepts-clients/#reader-interface). Whilst there is obviously a balance here, I think most (especially new) users would want to understand that there is a better way of processing messages than the documented `while(true)` loop. ### What is your suggestion? I would add something like the following: Messages can be processed by registering an implementation of a [ReaderInterface](https://pulsar.apache.org/api/client/2.11.x/org/apache/pulsar/client/api/ReaderListener.html) as follows: ``` Reader<byte[]> reader = pulsarClient.newReader() .topic(topic) .startMessageId(MessageId.latest) .readerListener((ReaderListener<byte[]>) (reader, msg) -> { // Process the message }) .create(); ``` ### Any reference? _No response_ ### Are you willing to submit a PR? - [X] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
