Description

The following code:

<?php

$metadata = new Metadata;
$metadata->getTopics()

Resulted in this output:

Exception : RdKafka\Metadata::__construct() has not been called

But I expected to get the topics list.

This might be misleading, you need to call an RdKafka or KafkaConsumer instance to get metadata, see doc Maybe docs or examples can be improved to make this more clear
