How Does Stream Processing Work?
- Stream processing is frequently used with data created as a sequence of events, such as data from IoT sensors, payment processing systems, and server and application logs.
- Common paradigms include publisher/subscriber (also known as pub/sub) and source/sink. A publisher or source generates data and events, which are then provided to a stream processing application.
- The data can be enhanced, evaluated against fraud detection algorithms, or modified before being sent to a subscriber or sink.
- Stream processing is often used interchangeably with real-time analytics, which is a relative word.
- Real-time could mean five minutes for a weather analytics tool, millionths of a second for an algorithmic trading program, or a billionth of a second for a physics researcher.
What is Stream Processing?
Stream processing is a technique for processing continuous data streams in real-time. Stream processing involves processing data continuously as it is generated, rather than collecting and processing it in batches. This method enables organizations to rapidly analyze and respond to data, making it particularly valuable for applications such as real-time analytics, monitoring, fraud detection, and recommendation systems.
