🔗 Virtual fields in Ecto: Eliminating N + 1 queries

There exists a plethora of things I find annoying in this world and slow sites certainly top the charts! But what causes increased latency when interacting with a database? In many cases, it is the dreaded N + 1 query problem; a scenario where an application makes multiple database queries instead of fetching all the needed data in a single query.

In the context of Ecto, a database wrapper for Elixir, using virtual fields can effectively mitigate this issue. With tools that Ecto provides, developers can streamline their database queries to be more efficient, enhancing the overall performance of their applications.
