As a witness, I am so proud. HBase also plays a pivotal role in this Crazy sales. One important application of taobao read 10Gbps and write 5Gbps data per second from HBase. Another incredible thing is that 1000 million trades has been processed in Alipay in one day, and even unbelievable thing is , they don't use Any IBM mini computers, instead, they only use 10 PCs with fusion IO devices in the trade database.

I understand you. But perhaps you are not familiar with the Chinese shopping habits and the situation now they faced with. High price good with heavy tax in the physical stores would be only sold with 50% discount in taobao online shops. If US could have such discount percentage, I believe that $5.6 could just be a small change
