Kafka consumer allows a few different ways to consume from the topics, including:

1. Subscribe from a collection of topics.
2. Subscribe to a topic pattern using Java Regex.
3. Assign specific partitions.

The KafkaSubscriber provides a unified interface for the Kafka source to support all these three types of subscribing mode.
