Request timeoutsedit

While you can specify Request time out globally you can override this per request too

we set up a 10 node cluster with a global time out of 20 seconds. Each call on a node takes 10 seconds. So we can only try this call on 2 nodes before the max request time out kills the client call.

var audit = new Auditor(() => Framework.Cluster
    .Nodes(10)
    .ClientCalls(r => r.FailAlways().Takes(TimeSpan.FromSeconds(10)))
    .ClientCalls(r => r.OnPort(9209).SucceedAlways())
    .StaticConnectionPool()
    .Settings(s => s.DisablePing().RequestTimeout(TimeSpan.FromSeconds(20)))
);

audit = await audit.TraceCalls(
    new ClientCall {
        { BadResponse, 9200 },
        { BadResponse, 9201 },
        { MaxTimeoutReached }
    },
    /**
    * On the second request we specify a request timeout override to 80 seconds
    * We should now see more nodes being tried.
    */
    new ClientCall(r => r.RequestTimeout(TimeSpan.FromSeconds(80)))
    {
        { BadResponse, 9203 },
        { BadResponse, 9204 },
        { BadResponse, 9205 },
        { BadResponse, 9206 },
        { BadResponse, 9207 },
        { BadResponse, 9208 },
        { HealthyResponse, 9209 },
    }
);

Connect timeoutsedit

Connect timeouts can be overridden on a per request basis.

Whilst the underlying WebRequest in the case of Desktop CLR and HttpClient in the case of Core CLR cannot distinguish between connect and retry timeouts, we use a separate configuration value for ping requests to allow ping to be configured independently.

We set up a 10 node cluster with a global time out of 20 seconds. Each call on a node takes 10 seconds. So we can only try this call on 2 nodes before the max request time out kills the client call.

var audit = new Auditor(() => Framework.Cluster
    .Nodes(10)
    .Ping(p => p.SucceedAlways().Takes(TimeSpan.FromSeconds(20)))
    .ClientCalls(r => r.SucceedAlways())
    .StaticConnectionPool()
    .Settings(s => s.RequestTimeout(TimeSpan.FromSeconds(10)).PingTimeout(TimeSpan.FromSeconds(10)))
);

audit = await audit.TraceCalls(
    /**
    * The first call uses the configured global settings, request times out after 10 seconds and ping
    * calls always take 20, so we should see a single ping failure
    */
    new ClientCall {
        { PingFailure, 9200 },
        { MaxTimeoutReached }
    },
    /**
    * On the second request we set a request ping timeout override of 2seconds
    * We should now see more nodes being tried before the request timeout is hit.
    */
    new ClientCall(r => r.PingTimeout(TimeSpan.FromSeconds(2)))
    {
        { PingFailure, 9202 },
        { PingFailure, 9203 },
        { PingFailure, 9204 },
        { PingFailure, 9205 },
        { PingFailure, 9206 },
        { MaxTimeoutReached }
    }
);
