Getting your data modeling wrong is one of the easiest ways to ruin your performance. And it’s especially easy to screw this up when you’re working with NoSQL, which (ironically) tends to be used for the most performance-sensitive workloads. NoSQL data modeling might initially appear quite simple: just model your data to suit your application’s access patterns. But in practice, that’s much easier said than done. 

Fixing data modeling is no fun, but it’s often a necessary evil. If your data modeling is fundamentally inefficient, your performance will suffer once you scale to some tipping point that varies based on your specific workload and deployment. Even if you adopt the fastest database on the most powerful infrastructure, you won’t be able to tap its full potential unless you get your data modeling right.
