The video by Gaurav Sen is about backpressure in the context of rate limiting.
The discusses two methods, onAccept and onReject, responsible for handling client calls.
The client is responsible for running these functions on a low-priority thread.
The algorithm discussed in the video is a sliding window algorithm that reduces the sliding window size by one if a request fails.
The size of the sliding window is defined by a threshold, and the time unit is determined by the server.
We suggest using an enum time unit to ensure that the client and server have the same representation of time units.
Finally, we discuss the need for an independent object to make the algorithm more scalable.
