Trying out a few ways to throttle API GET requests...

Trying out a few ways to throttle API GET requests. The `debounce`/`sample` operators for Flow don’t work as desired, so what I need is more of a throttleFirst . Tried with using async and returning null when the request should be throttled:

class ApiClient {

    private var deferredLoad: Deferred<Result>? = null

    suspend fun load(throttleMillis: Long = 300): Result? {
        return coroutineScope {
            if (deferredLoad?.isCompleted != false) {
                async {
                    val result = /** make GET API call **/
                    delay(throttleMillis)
                    result
                }
                .apply { deferredLoad = this }
                .await()
            } else {
                null
            }
        }
    }
}

Is this approach recommended? Finding it a little weird to hold on to a var of Deferred , thinking it might need a Mutex. Wondering if there’s a more elegant approach that others have found?

might be easier to throttle it at 3req/second instead of playing around with delays
