Someone's never done a data migration while serving 1M+ qps!
I feel like I would try to strangle the old app (putting proxies in front and redirecting endpoints as they're rewritten) rather than swapping it out wholesale.
At that point I don't know if it really counts as a migration as much as just development.
Any thoughts on that approach? Is that what you have done, or was it a more holistic swap over?
They did. They even tossed out Common Lisp and bought in Python because they thought it would fix their problems. It didn't.
The problems they're dealing with 14 years later as one of the top sites on the internet aren't even slightly comparable.
Python is a good scripting language, But if you are developing backend applications for this scale you probably need some serious JVM language. Or even Golang works fine.
You make plenty of baseless assumptions about my background and ambitions... but I'm not even going to try to address my professional experience (or lack thereof) because it doesn't matter, since you're just using it as a straw man to deflect criticism.
The facts are as follows: 1. Reddit is one of the highest visited websites in the world. 2. Throughout nearly their entire history, they've struggled to put together a way to make money. 3. They have notorious uptime.
Of course they have talented engineers... it would be a surprise if one of the worlds most popular websites didn't.
That doesn't change the facts that they continue to look and function like they're straight out of 2005 (does their search even work yet?), lack a semi decent mobile experience, and have contributed essentially nothing to the technical community in their entire history.
True, but irrelevant. It also means they handle more traffic per dollar than probably any other site in it's category.
> They have notorious uptime.
Browsing https://reddit.statuspage.io/ for less than a minute proves this is hyperbolic bull.
> and have contributed essentially nothing to the technical community in their entire history
It's not like the reddit source code hasn't been open source forever. But sure, whatever you say. Would have taken you 10 seconds to Google before spouting off nonsense.
Other big players like Facebook, Twitter, etc, are literally inventing pivotal parts of the modern web technical stack. What has come out of reddit?
