Conquer Apache Kafka 2025 – Dive into Data Streaming Dominance!

A Kafka topic is defined as a category or feed name to which records are published. In Kafka, a topic acts as a logical channel that segments and organizes data streams. Producers write records to a specific topic, while consumers read records from that topic. This organization allows for efficient categorization of data and is essential for the publish-subscribe pattern inherent in Kafka's architecture. Each topic can have multiple partitions, which enables parallel processing and scalability, ensuring that data can be distributed and consumed effectively.

The other options do not accurately capture the essence of a Kafka topic. While user session management and inter-service communication are vital parts of many systems, they do not relate to what a topic is within Kafka's messaging framework. Additionally, the primary storage for all Kafka data would refer more broadly to log files and brokers rather than the categorized nature that a topic provides. Thus, defining a Kafka topic as a specific category where data records are published and consumed encapsulates its core function and importance in Kafka's design.
