Strategy Analysis: Fixed Window
Pros
- Easy to implement.
- Low memory usage.
Cons
- Can lead to "thundering herd" problems at window boundaries.
- Uneven traffic distribution.
Throttling Behavior
Requests are rejected once the limit for the current window is reached. The counter resets at the start of the next window.
