If the user has no objection to B, the scope is gradually expanded, migrate all users to B. Gray release ensures the stability of the entire system. problems can be detected and adjusted

1. Demand Analysis There are many ways to handle access control by Nginx, and there are many kinds of effects, such as accessing IP segment, accessing content restriction, accessing frequency limit and so on.Using Nginx+lua+redis to make access restrictions is primarily to take into account the need for fast access control in high concurrency environments.The process of Nginx processing requests is divided

The Redis 2.6.0 built-in Lua script support allows you to run a lot of logic once on the server side of Redis. The entire script is in one transaction by default. All the keys involved in the script are passed in as far as possible from the outside, so that Redis knows what key you want to change from the

Objective Lua is a scripting language known for its performance and is widely used in many ways, especially games. Like "World of Warcraft" plug-ins, mobile games "big Masters" "The Divine Comedy", "The Lost Land" and so on are written in Lua logic. So most of the time we don't have to think about performance.
