The convenience and power of Active Record allows you to interact with your database in a more Ruby-like way, making it easier to write efficient and readable code. However, as with any complex system, performance can sometimes take a hit when using Active Record. One common scenario where performance may suffer is when counting records in your database. In any Rails app, A simple count method call can quickly become a bottleneck, especially for larger datasets. In this post, we’ll dive into some optimization techniques for using Active Record’s count method in your Rails app.

Ruby is such an expressive language. You can often do surprisingly much with just a few lines of code. It’s why I find it so satisfying to think about how to accomplish the same thing in fewer lines of Ruby1. If we accept the claim that that number of bugs correlates with number of lines of code this is not just a fun exercise. There’s real business value in accomplishing a feature with less lines of code. ↩
