in a loop.The setinterval is loop-activated, that is, each time interval is set to trigger the specified code. This is the real timer.SetInterval is simple to use, while settimeout is more flexible, can exit the loop at any time, and can be set to run at an irregular interval, such as the first 1 seconds, the second 2 seconds, the third time 3 seconds ...Reference article:http://heisetoufa.iteye.com/blog/269566Http://www.cnblogs.com/mbtq/archive/2012/10/25/2740023.htmlHttp://blog.sina.com.cn/s/
The 2014 Rice Noodle FestivalIn the early hours of April 9, 2014, my colleagues and I made a final inspection and walkthrough of the snapping system for Xiaomi nets. A few hours later, the first major event of the year, the Rice Noodle Festival, is about to begin.The Rice Noodle Festival is an important examination for the adult rite of Millet e-commerce.

E-commerce's second kill and snapped up, for us, is not a strange thing. However, from a technical point of view, this is a huge test for web systems. When a web system receives tens or even more requests within a second, the optimization and stability of the system is critical. This time we will focus on the technology implementation and optimization of the second kill and snapping, at the same time, from the technical level, why we are always not ea
Snapping, second-kill is now a very common application scenario, there are two main issues to solve:1 high concurrency pressure on the database2 How to deal with the correct reduction of inventory ("oversold" issue) under competitive statusFor the first question, it is easy to think of caching to handle snapping, avoiding direct manipulation of databases, such as Redis.The focus is on the second question.Ge

Challenges posed by large-scale concurrencyIn the past work, I have been faced with 5w per second high concurrent kill function, in this process, the entire web system encountered a lot of problems and challenges.

Snapped up, second kill is now a very common application scenario, the main problem to be solved are two: 1 high concurrent pressure on the database 2 How to solve the correct inventory reduction ("oversold" problem) in the competitive state For the first question, it is already easy to think of using caching to handle snapping, avoiding direct manipulation of databases, such as using Redis. The focus is on the second question. General wording:
Just saw a buddy wrote a jquery plugin countdown-buy seconds kill suddenly think of an idea is titleIdea: Now many places have similar seconds to kill, snapping, such as speed, speed (in fact, the server slag, such as: a meter), many people think can write a client, open has been brush,I think I should be able to directly through the JS code to execute.

The company wants to do a snapping up function How can I avoid the extra order of concurrent orders? Because the database is MONGO can't lock like MySQL Do not know what a good solution? All I want to do is use Redis to force him to line up, but this is ridiculous.Every time I create it, I check it out, but I'm afraid there's a concurrency.
