Practical Real-time Data Processing and Analytics

Real–time analytics – the myth and the reality

One of the biggest truths about the real–time analytics is that nothing is actually real–time; it's a myth. In reality, it's close to real–time. Depending upon the performance and ability of a solution and the reduction of operational latencies, the analytics could be close to real–time, but, while day-by-day we are bridging the gap between real–time and near–real–time, it's practically impossible to eliminate the gap due to computational, operational, and network latencies.

Before we go further, let's have a quick overview of what the high–level expectations from these so called real–time analytics solutions are. The following figure captures the high–level intercept of the same, where, in terms ...
