Burst limit vs rate limit. Jul 23, 2025 · Both API throttling and API rate limiting serve as effective tools for controlling API traffic. The rate at which our bucket gets refilled with tokens is called the rate limit. This is particularly useful for initial data fetching scenarios. Upon catching such exceptions, the client can resubmit the failed requests in a way that is rate limiting. Burst Limit: A burst rate of 10 requests per second is allowed, enabling quick succession of calls without hitting the per-minute cap immediately. Throttling is better suited for managing fluctuating loads and ensuring service continuity, while rate limiting is ideal for protecting resources from abuse by enforcing strict limits. . Apr 30, 2025 · Every token represents 1 API gateway request. When request submissions exceed the steady-state request rate and burst limits, API Gateway begins to throttle requests. The amount of tokens that our bucket can contain is what we call the burst limit. For example, you might want to permit a total of 1000 calls per hour (rate limit) and a maximum spike of 50 calls per second (burst limit). Firstly from the definition [1]: A burst limit represents the maximum number of concurrent requests at any given time, while a rate limit defines the number of requests allowed per second. Configuring a burst limit prevents usage spikes and ensures that the rate limit is evenly spread across its overall time period. Clients may receive 429 Too Many Requests error responses at this point. wtp gzv cbecf esrvxv pqecpbb vjs htbwnv edwx gcakwpn amljy
