High concurrency
When it comes to "high concurrency", I believe you should be familiar with it! At this time, you should have a lot of high-concurrency issues in your mind: rapid business growth, e-commerce shopping, e-commerce spikes, 12306 ticket grabbing, various activities on Taobao and Tmall, etc.; all of which require high concurrency, so how to do it ? What about designing a high-concurrency system to withstand these shocks?
In fact, this is also a very common interview question, but most applicants don't know how to answer it and where to start. For a Java programmer, is he more concerned about the system architecture level ? From the original timing spike, to the preheating of various activities, group joining, deposit expansion, tens of billions of subsidies, cross-store full discounts and more complex combination discounts, users are confused, although these have disrupted user purchases . The rhythm, but it has also maintained a state of continuous heating.
In today's Internet age, high concurrency is a very common problem. So, what kind of system is a high-concurrency system? Today, let's decrypt the architecture of a typical seckill system in a high-concurrency scenario with LZ to see how much you know?
Today, in order to answer questions, LZ has prepared a high-concurrency system design manual, which is divided into seven parts: basics, databases, caches, message queues, distributed services, maintenance, and actual combat; take you from the basics to actual combat
