2TB is in no way a limit
I would agree, it's just I don't jump to recommend it at that level.
A database that size usually has other ...... complications?

Basically is what had been said previosly postgress is good for small
business database not for bigger,
personally I still found postgress better than mysql, based on what I read :).
I've worked with both.
I can make mysql outperform any database, including Oracle, on any
dataset under 2TB. What I cannot do is make it ACID compliant and
perform like that. mysql was originally designed for throughput, all
transaction stuff is an addon and it shows.
The reason Uber went to mysql is they don't care. Throughput is most
important to them. They can afford to deal with the inconsistencies
because of the mass of data they have. After all most of their money
comes from selling your trip data. And I'll bet you their payment
processing system is not on mysql.
Oh no I used an abbreviation, I never even went to geek schoool. Calm
down, I can do this:
A - Atomic?
C - Complete I know this one :)
I - Independant Know this one 2
D -
This is why I'm on the internet someone knows what the D is for, :)
