Data streaming is the continuous flow of data that is generated and transmitted in real-time. This process allows information to be sent and received instantly, making it possible for applications to process data as it arrives. For example, when you watch a live video on YouTube, the video is streamed to your device, allowing you to watch it without waiting for the entire file to download. In many industries, data streaming is crucial for tasks like monitoring social media trends or analyzing financial markets. By using data streaming, businesses can make quick decisions based on the latest information, improving their responsiveness and efficiency.
