Can you list the main components of the Kafka system and explain their purpose?

Main components of the Kafka system and their purpose:

• Broker — Kafka server that stores data and handles requests for writing and reading messages.
• Topic — a logical category or channel where messages are published. Topics are divided into partitions for scalability.
• Partition — a part of a topic that stores a sequence of messages. Each partition is ordered and has offsets.
• Producer — a component that sends messages to Kafka topics.
• Consumer — a component that reads messages from topics.
• Consumer Group — a group of consumers that jointly read data from topics, ensuring load balancing.
• Zookeeper — a service that manages Kafka metadata, coordinates brokers, and monitors their status (in newer Kafka versions, a native mechanism without Zookeeper may be used).

Example: A producer sends events to a topic, the broker stores them in partitions, and a consumer group reads these events for processing.
