When fetching records from Kafka bootstrap servers, we can specify one consumer to subscribe to more than one topic. This can be done in the init function by passing a list of topics:

topics = ['kontext-events', 'other-events']
    bootstrap_servers = 'localhost:9092'
    consumer = KafkaConsumer(

Alternatively, we can use subscribe() function to subscribe to multiple topics. We can also regular expressions to match topics via patterns:

subscribe(topics=(), pattern=None, listener=None)
