Kota is a simple rate limiter.

Basic example

{:ok, kota} = Kota.start_link(max_allow: 10, range_ms: 1000, adapter: Kota.Bucket.DiscreteCounter)
:ok = Kota.await(kota)

Adapters

• Kota.Bucket.DiscreteCounter – This adapter just counts every call at the expense of memory usage.
• Kota.Bucket.SlidingWindow – This adapter uses a sliding window technique to save on memory and processing but will result in a lower rate if used constantly without time to recover time lost by the window timespan.
