The 5-Second Data Delay That Nearly Broke Us (And How We Fixed It in Milliseconds) | HackerNoon
Briefly

The article outlines a team's struggle to develop a real-time dashboard for monitoring transactions on a financial platform. Initially, they employed a traditional batch approach that led to unacceptable latency, sometimes reaching several seconds, which is impractical in a financial context. A demo revealed significant delays, which prompted the need for urgent changes. The authors detail the missteps in their approach, highlighting the gap between a system that seems to work and one that actually meets the requirements of real-time analytics, ultimately recognizing the need for more immediate data processing solutions.
When 'Real-Time' Wasn't Really Real-Time. I remember vividly our CTO's reaction during the first demo. 'Why is there such a lag?' he asked while pointing at the dashboard.

We opted for lower than 1-second latency. What we provided was a system that sometimes, during surges of traffic, was as far behind as 3-5 seconds.

Some drastic changes were required and required fast. Our First Attempt: The Traditional Batch Approach.

It is problematic that 'working' and 'fulfilling' are two terms that are completely divorced from each other.
