What do you know about Apache Kafka?

Apache Kafka is a distributed data streaming platform designed for processing large volumes of messages in real-time. It functions as a high-performance message queue with data storage and replication capabilities.

Key features of Kafka:

• Messages are organized into topics, which are divided into partitions for scalability.
• Support for publish-subscribe with message order guarantee within partitions.
• High performance and fault tolerance through replication and distributed architecture.
• Used for building event processing systems, logging, and microservices integration.

Example of use: a service publishes user action events to a Kafka topic, and other services subscribe to these events for analytics or data updates.
