In the Rails ecosystem, every developer knows about the so called N+1 query problem and how to deal with it. It is about impossible today to overlook tons of articles, blog posts, and tutorials mentioning both the problem and the solution to it.

The N+1 problem is a common performance anti-pattern. It happens when we fetch records from an associated table not with a single SQL query but instead using individual queries for every single record.

class User < ActiveRecord::Base
  has_many :messages

class Message < ActiveRecord::Base
  belongs_to :user
end

export const _frontmatter = {}
