The technology used for real-time data streaming is Apache Kafka. It is an open-source platform designed for high-throughput data pipelines and enabling the seamless transfer of data between different systems. Kafka provides a publish-subscribe model, allowing producers to send messages to a topic from which consumers can subscribe and receive messages in real-time. Its capabilities make it ideal for applications that require live data feeds, such as analytics, monitoring, and event sourcing. Many organizations utilize Kafka for building scalable and fault-tolerant systems.
