  A rate limiter is a mechanism used to control the rate at which requests are sent to a server or an API (Application Programming Interface). It is used to prevent abuse, misuse, or excessive use of a system's resources, and to ensure that a system is able to provide consistent and reliable service to its users.   The main advantages of using rate limiting include:  Preventing abuse : Rate limiting can help prevent malicious attacks or excessive use of a system's resources, such as a Denial of Service (DoS) attack or brute force login attempts. Ensuring service availability: By limiting the rate of incoming requests, rate limiting can help ensure that a system is able to provide consistent and reliable service to its users, even during periods of high traffic.   Managing costs: Rate limiting can help manage costs by limiting the use of expensive resources, such as processing power, network bandwidth, or database queries.   However, there are also s...
