> In the 2000s, the conventional wisdom selected MySQL because rising tech stars like Google and Facebook were using it. Then in the 2010s, it was MongoDB because non-durable writes made it “webscale“. In the last five years, PostgreSQL has become the Internet’s darling DBMS. And for good reasons!
Different DB's, different strengths and it's not a zero sum came as implied. MySQL was popular before Google was born - we used it heavily at eToys in the 90s for massive transaction volume and replacing it with Oracle was one of the reasons for the catastrophic failure of eToys circa 2001. MongoDB gained traction not because it's an alternative to MySQL or PostgreSQL. And PostgreSQL's marketshare today is on a par with Mongo and both are dwarfed by MySQL which IMO is the true darling of web DB's given it's global popularity.
did google even use mysql? certainly if they did they never talked about it publicly in the early 02000s, and of course facebook didn't even exist then
lj, though, they used the fuck out of mysql
/. originally didn't use a database; i (an ordinary user) accidentally posted an article by trying to post a comment on an article that didn't exist yet; i guess they got appended to the same file. but when it did switch to a database (i don't know, about the time google was founded?) it was of course mysql
