RethinkDB versus PostgreSQL: my personal experience
>Everything is an order of magnitude more efficient using PostgreSQL than it was with RethinkDB.A large part of the sales pitch of "NoSQL" was that traditional RDBMSs couldn't handle "webscale" loads, whatever that meant.Yet somehow, we continue to see PostgreSQL beating Mongo, Rethink, and other trendy "NoSQL" upstarts at performance, one of the primary advantages they're supposed to have over it.Let's be frank. The only reason "NoSQL" exists at all is 20-something hipster programmers being too lazy to learn SQL (let alone relational theory), and ageism--not just against older programmers, but against older technology itself, no matter how fast, powerful, stable, and well-tested it may be.After all, PostgreSQL is "old," having its roots in the Berkeley Ingress project three decades ago. Clearly, something hacked together by a cadre of OSX-using, JSON-slinging hipster programmers MUST be better, right? Nevermind that "NoSQL" itself is technically even older, with "NoSQL" systems like IBM's IMS dating back the 1960s: https://en.wikipedia.org/wiki/IBM_Information_Management_Sys...
