Yeah, horrible legacy projects that are a pain in the ass to maintain
Source: I am working on a legacy API based on a noSQL database with a very dumb design (because the data was relational of course) in a very large company
How can a "legacy" project be using noSQL? In my company, "legacy" projects are projects that have been around for 10+ years. MongoDB hasn't even been out a full 10 years, yet...
A project doesn't need to be 10+ years old to be legacy.
This API is 3y old, and was the first iteration, the v1, of the company's digital asset management API, it's only maintained for a few teams around the world, whereas the v2 is well crafted and has a way more logical datamodel
Legacy != old
