Ask HN: How to Wield NoSQL Databases

Don’t worry HN, I still love postgres, but I’ve recently learned that while I’ve been nice and cozy in my relational world, I have little awareness of noSQL databases

things i’ve stumbled upon: - using redis ordered sets to rank things - dynamodb single table design - in a system design interview i was asked how to prevent data corruption from two requests targeting the same key

it seems as though there’s a whole world where all the noSQL companies are trying to solve all the problems that relational db had solved.
