I've noticed that my codebase has a lot of instances of the n+1 query problem after going back to refactor some parts. Is this something that happens often in projects, and how should I approach it?

Definitely normal! You need to recognize these patterns and address them proactively. Regular checks on what queries are being executed can save you a lot of headaches down the line.
If you're using GraphQL, it's pretty common to hit this snag during the initial implementation. Consider adopting a data loader to help manage queries better, but I found that it's sometimes slow. What worked for me was flattening the queries and controlling how data was fetched, which significantly improved performance.
Yep, this is quite the usual scenario! Most codebases I've seen suffer from n+1 queries due to lazy loading in ORMs. It's essential to spot these issues early and actively fix them, so keep an eye on your query performance.
Absolutely! The n+1 query problem often crops up, especially in codebases that grow without careful query management. It's super easy to introduce this kind of issue with ORMs because of lazy loading. To tackle it, start by implementing query logging to identify the worst offenders, then move to eager loading or joins to resolve them. Sometimes, a complete restructuring of how related data is retrieved might be necessary.
Hitting n+1 queries is pretty standard, especially if your code evolved without attention to query efficiency. But don’t freak out too much—examine your query performance and strive to improve it when necessary.
