Distributed outbound http rate limiter

QUESTION

Distributed outbound http rate limiter

Asked 2019-Jul-01 at 08:46

I have a microservice architecture application with multiple services polling an external API. The external API has a rate limiter of 600 requests per minute. How can I have all of my instances together stay below the shared 600 rate limit?

Google only brought me 3 solutions, the most promising being:

myntra/golimit the most promising of the three, but I literally do not have a clue how to set that up.
wallstreetcn/rate which only seems to reject when limit has been reached (my app needs to wait till it can make the request) and the Every function in the rate.NewLimiter func seems to be a different import / dependency which i cannot figure out which it is
manavo/go-rate-limiter has a "soft" limit which, obviously, could get me over the limit. Some endpoints I dont really mind if I cant access them for a few seconds, but other endpoint requests should work as much as possible.

Currently I have an amateur solution. The code below allows to me set a limit per minute and it sleeps in between requests to spread the requests over the minute. This client rate limit is per instance, thus I would have to hardcode divide the 600 requests by the amount of instances.

if you want a global rate limiter, you need a place to maintain distributed state, such as zookeeper. Usually, we don't want to pay the overhead. Alternatively, you can set up a forward proxy (https://golang.org/pkg/net/http/httputil/#ReverseProxy), do rate limit in it.
