Hello guys, we are trying out the RateLimit functionality and we can’t get it work as we expected.

Here is how we set up the client:

private fun client(uri: Uri): HttpHandler =
    SetBaseUriFrom(uri)
        .then(RateLimit())
        .then(OkHttp(okHttpClient(100)))

Note: It’s using the default RateLimitConfig which is documented as By default, handles maximum of 50 requests per 5 seconds.

Here is how we are testing this out:

fun main(){
    val timeTaken = measureTimeMillis {
        makeMultipleRequests(51, client(Uri.of("<http://localhost:3002/some-url>")))
    }
    println(timeTaken)
}

I would expect the time taken to be greater than 5 seconds? Is this is how it’s suppose to work?

Running it a few times to get an average it seems to complete in around 2-3 seconds.

Thanks in advance

hey. it's been a while since I used the rate limiter, but I think the best bet for this is to check out the resilience4j docs as that's the underlying library that we're using

[dave]

we just delegate down to it so any quirks will be those of the lib: https://github.com/resilience4j/resilience4j

OK thanks for this, just to be sure the way the client is set up with the filters, does that look correct to you?

[dave]

yep - it's all pretty simple - not much to hide! 🙂

[dave]

but let us know how you get on 🙂
