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.
