Houston, we have problems with the queries

Thu, 29 Jan 2026 07:00:02 +0000

introduction

Most developers build queries to access a relational database, using some ORM in different ways to generate the query automatically or write the query manually. Everything could work in most cases in other environments, but at some point, the query becomes slow, or the application takes more time to execute the same task that it did in the past. At this point, the developers, QA, and many others waste a lot of time understanding the change that produced the problem in the last commits, but why not create a test that detects some issues with performance before they appear?

introduction

Multiple developers may introduce changes to develop new features or fix bugs during an application’s life. At the same time, these changes could introduce problems in the code, such as bad practices regarding the declaration of attributes, duplicate code, or pieces of code with a high risk of producing errors.

In many cases, this situation could be detected on a peer review of the code for another developer but implies that someone needs to spend too much time focusing on small details instead of focusing on the problem that the code tries to fix. The appearance of tools like PMD, Checkstyle, SonarLint, and many others that detect problems analyzing the code mitigates most of the problem, but let’s see in detail the impact on the day-to-day of the company or developer.
