Yet another record.
Three minutes and one second! That's how long it took Alibaba to pass the 10-billion-yuan mark in sales on its flagship Tmall e-commerce platform at this year's Double 11 shopping bonanza, beating last year's record by 3 minutes 57 seconds.

Big data battlefield
The Double 11 has become a battlefield not only for merchants and shoppers but also for engineers.
Millions of people simultaneously rushing to apps to grab the best bargains puts a major strain on servers. In previous years people have failed to confirm their payments in the first few minutes as they try to be the first to land the best offers promised by vendors.
In 2013, Alibaba carried out a major program called " full link stress test," which stimulated real online users to check whether the system could handle the pressure at midnight.
However, engineers failed to get the results they wanted in the first three years.
This year, however, they came up with "Project Vanguard," an unmanned stress test. Many procedures were carried out by an AI system, which decides what the user volume would be, what the scale of pressure is and what countermeasures should be put in place.
Even with all this technological wizardry, some users still experienced difficulties locking down their purchases in the first two minutes this year.

Chinese may spend more in one day than Americans in 3 (Thanksgiving+Black Friday+Cyber Monday), even on Per Capital sense. This is actually a bigger event than what most people realize.
