It basically sets key to hold string value if key does not exist In that case, it is equal to set When key already holds a value, no operation is performed Here's an example of a policy that limits the calls to 1,000 per minute. Learn essential rate limiting and api throttling strategies with code examples in node.js, python, and nginx Master techniques for protecting web services, preventing abuse, and ensuring optimal performance.
Rate limiting is like setting a speed limit on that busy highway With rate limiting, you define the maximum number of requests a client can make to your api within a specified time window, such as requests per second or requests per minute. Api rate limiting is used to protect web resources and services by preventing the frequency of transactions from exceeding a set maximum number In this article, you’ll learn What is rate limiting in application design Users interact with application resources by sending requests.
Rate limiting offers several important features Easy to understand and implement flexibility Adapts to different use cases performance Optimized for production environments reliability It’s simple to implement at both the network and application level If someone is trying to flood the system with requests, limiting their ip can prevent this
Attackers can use techniques like vpns, proxy servers, or even botnets to spoof different ips and get around the limit.
