What are you referring to?

Lazy loading in Rails tends to refer to how Active Record waits until access time to send the query: https://rubyinrails.com/2014/01/08/what-is-lazy-loading-in-r...

It's still synchronous.

Django has this type of lazy loading as well: https://docs.djangoproject.com/en/2.1/ref/models/querysets/#...
