In this talk, we'll discuss how companies are using, monetizing, and productizing, real-time analytics. You'll get a clear breakdown of use cases, and overview of streaming technology, how stream processing compares to batch. We'll wrap up with a quick demo showing real-time analytics in action, using Kafka stream processing and RisingWave, a SQL stream processing DB, and a visualization tool, giving Java developers practical insights into using streams for faster, more efficient data processing.
