“A platform built on Apache Flink at Alibaba was officially launched in 2016, involved in two big use cases: search and recommendation. Currently, more than one trillion events are processed on Flink each day. Flink can process over 472 million transactions per second during business peaks, which is truly astronomical. One of the most notable of application scenarios is the Alibaba data dashboard during Double 11* events.”
-Feng Wang, Alibaba
*Double 11, also known as Singles' Day, is a 24-hour online shopping festival that takes place on November 11th each year. It's a global retail phenomenon that originated in China as a day for singles to celebrate their independence.
