Throttling Pattern

Comments

Use throttling to stop services in order to reduce usage i.e. task manager close tasks in order to free resources but recover task once resources are available

Code

Simple REST API throttling TODO: service/application level throttling

public class ThrottledRestClient : RestClient
{
    private readonly int _requestsPerMinute;
    private int _lastRequestTime;

    public ThrottledRestClient(int requestsPerMinute)
    {
        _requestsPerMinute = requestsPerMinute;
    }
    public override IRestResponse Execute(IRestRequest request)
    {
        int elapsedTime = Environment.TickCount - _lastRequestTime;
        int pause = (60/_requestsPerMinute)*1000;
        int wait = pause - elapsedTime;
        if (wait > 0)
        {
            Thread.Sleep(wait);
        }
        var response = base.Execute(request);
        _lastRequestTime = Environment.TickCount;
        return response;
    }
}
