Subscribe to Multiple Topics in Kafka Consumer

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( *topics, client_id='local-test', bootstrapservers=bootstrapservers, autooffsetreset='earliest' ) ` 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) ``

Kafka Consumer - Fetch Records from Beginning

This code snippet reads data from topic's beginning offset by utilizing seektobeginning() API. This will sets each partitions subscribed by the consumers to fetch records from the earliest available offsets. Example output: polling... Kontext message 1 Kontext message 2 Kontext message 3 Kontext message 4 Kontext message 5 New kontext events~!! New events! polling... polling...

Python - Read Messages in Kafka Topic

This code snippet provides example of reading messages from Kafka topics. In common practices, one Kafka consumer is used to read from one partition for a topic; if there are multiple partitions for the same topic, each consumer can run in different servers or containers. Those consumers for different partitions are also configured within one consumer group. In this example, all partitions are assigned to the same consumer. This code snippet utilize Python package kafka-python. It can be installed via the following command if you have pip installed: `` pip install kafka-python ` Or we can also use built-in pip in Python 3: ` python -m pip install kafka-python `` References Apache Kafka Python Producer and Consumer Clients Introduction Install and Run Kafka 3.2.0 On WSL Install and Run Kafka 2.6.0 On Windows 10
