Hi,
I came across a question which says
Design Flipkart Flash sale architecture. 2 million hits and 20k orders in 2 sec. Find out database scalability.  
Now here if we forget about what is flash sale. And some simple application with 2 million hits and 20k orders in 2 sec.
What is this database scalability all about ?
I have made small applications with not so many hits and have always used mysql database.

Thanks

>>Database scalability revolves around disk writes.

Sorry but I have to disagree.  It has to do with ALL resources involved as the application/usage grows.
