yeah, i was surprised at the cluelessness of that remark. lamp was definitely not a 'rising tech stars' thing. hopefully the author is more careful about accuracy when it comes to database architecture than when it comes to www history

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

MySQL (then Vitess) ran Youtube, but nowadays I do believe most product teams are using Spanner.

Yeah I think (heard anecdotally) both google/YouTube and Facebook (and many others) started with MySQL. Spanner for distributed writes has inspired most implementations although Google is the only one I know about that implements TrueTime (atomic clocks). The same year that the Spanner paper came out (after Percolator) an alternate approach (Calvin) was also published, and some of us are using that (our DB's design is inspired by it, but we've done a lot of enhancements since then).

youtube did, but google didn't buy youtube until three years before the end of 'the 2000s'
