What is a Data Stream?

A data stream is a continuous flow of data generated in real time from various sources such as sensors, user interactions, social media feeds, or financial transactions. It involves the collection and transmission of data in a constant, real-time manner, often used for applications that require immediate analysis and action.

Data streams are critical in scenarios where time-sensitive decisions are necessary, such as monitoring website traffic, tracking stock prices, or detecting fraudulent activities. Processing data streams efficiently allows businesses to gain immediate insights, respond to events as they occur, and optimize operations in real time.
