allows people to quickly receive goods. As time went on, MongoDB grew up. They solved the architecture problem one by one, and now it's an excellent product. It may not be as perfect as we want it to be, but it does its job very well. In the 2014 we were clearly aware that we were at a disadvantage in the competition, and we tried to differentiate it from MongoDB. We found a very elegant way to add real-time push, hopefully allowing developers to build a generation of applications that they cou
