RethinkDB versus PostgreSQL: my personal experience
>Everything is an order of magnitude more efficient using PostgreSQL than it was with RethinkDB.<p>A large part of the sales pitch of "NoSQL" was that traditional RDBMSs couldn't handle "webscale" loads, whatever that meant.<p>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.<p>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.<p>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 <i>MUST</i> be better, right? Nevermind that "NoSQL" itself is technically even older, with "NoSQL" systems like IBM's IMS dating back the 1960s: <a href="https://en.wikipedia.org/wiki/IBM_Information_Management_System" rel="nofollow">https://en.wikipedia.org/wiki/IBM_Information_Management_Sys...</a>
