Publishing and Subscribing to Kafka Topics
Kafka topics are fundamental to its messaging system. Producers send data to a topic, while consumers read from it. Kafka's Producer API facilitates the publishing of messages, allowing users to define the topic, key, and value. For data consumption, the Consumer API enables subscribing to topics, reading messages, and managing offsets. Offsets are critical as they track the consumer's position within a topic, ensuring no data is missed. Kafka supports various serialization formats, including JSON and Avro, making it flexible for different data types and structures.
