What is Kafka used for?

Kafka is a distributed messaging system that is high throughput and low latency, designed for processing real-time data streams. It helps developers build scalable and fault-tolerant data flow applications using a publish-subscribe model to store and transmit data as messages, enabling asynchronous communication between different components. Kafka is widely used for scenarios such as log collection, event-driven architecture, stream processing, metric collection, and real-time data pipelines. It is highly reliable and scalable, capable of handling large-scale data streams while ensuring message ordering.
