Understanding N and 1 queries problem

• ffi-overhead

  19 645 0.0 C

  comparing the c ffi (foreign function interface) overhead on various programming languages

Piling on about overhead (and SQLite), many high-level languages take some hit for using an FFI. So you're still incentivized to avoid tons of SQLite calls.

  A lightweight function-oriented toolkit for better organisation of business logic and efficient selection and projection of data in Django projects.

  

We solved the N+1 queries problem where I work by raising the level of abstraction from "queries plus serialisation" to "what shape data is required". We open sourced the solution at https://www.django-readers.org/.

• bullet

  28 7,002 7.0 Ruby

  help to kill N+1 queries and unused eager loading

There's a Ruby gem called Bullet that identifies and warns developers about N+1 problems. You can also have it fail tests if detected.

I don't know if the approach is possible with every ORM or if it's just leveraging some Ruby perks, but I can't think of a good reason why you wouldn't use the equivalent everywhere.
