Which algorithm ratelimit process is using ?

I am not able to find in the documentation which strategy is using the process to rate-limit.

Token bucket, Leaky bucket , Fixed window, Sliding window

thanks

It's Fixed Window at the moment:

ratelimit/src/limiter/cache_key.go

Line 73 in edab0ec

b.WriteString(strconv.FormatInt((now/divider)*divider, 10))

There's a PR for Sliding Window that's been open for many months, gone stale, and been closed.
Also see #32

And why we are not considering token or leaky bucket as we do in local rate limit?
What would be the difference? I don't think consistency is needed here.
