Course Introduction：Throttling is a common strategy to prevent system overload. By limiting the system's request rate, the availability of the system can be guaranteed and data loss caused by system crashes can be prevented. In actual engineering applications, current limiting is often needed to ensure system stability. This article will introduce how to use golang to implement the current limiting function. 1. Current-limiting algorithm Current-limiting algorithm refers to an algorithm that controls traffic in some way. Using a current-limiting algorithm in a program generally means controlling the processing speed of the program. Common current limiting algorithms include leaky bucket algorithm and token bucket algorithm. Leaky Bucket Algorithm: Leaky Bucket

Course Introduction：High-concurrency systems have three weapons: caching, downgrading, and current limiting; the purpose of current limiting is to protect the system by limiting the rate of concurrent access/requests. Once the rate limit is reached, it can deny service (direct to an error page), queue and wait ( Flash kill), downgrade (return to bottom-up data or default data); common current limits in high-concurrency systems include: limiting the total number of concurrencies (database connection pool), limiting the number of instantaneous concurrencies (such as nginx's limit_conn module, which is used to limit the number of instantaneous concurrent connections) ), limit the average rate within the time window (nginx's limit_req module is used to limit the average rate per second); in addition, the current can also be limited based on the number of network connections, network traffic, cpu or memory load, etc. 1. The current limiting algorithm is the simplest and crudest

Course Introduction：In daily development, we often face high-concurrency scenarios, and strict current limiting is particularly important at this time. In Golang, a common way to implement current limiting is to use a timer (Timer) to limit the number of concurrent requests by controlling the trigger time of the timer. This article will introduce how to use Golang's timer to implement current limiting. 1. What is a timer? In Golang, Timer is a system-level timer. You can create a timer to trigger tasks or events regularly. When creating a Timer, you need to specify
