Real-Time Analytics Explained

Real-time analytics hinges on the freshness of data, which can vary from seconds to minutes depending on the application. Dhruba highlights the distinction between data latency—how quickly data is available for decision-making—and query latency—the time it takes to receive results after issuing a query. In scenarios like food delivery, low data latency is crucial for timely responses, while logistics over longer distances may allow for slightly higher latencies. Ultimately, real-time analytics are predominantly online systems that must react swiftly to avoid negative impacts on business and user experience.
