Learn Orleans 05 - MultiGrain

https://github.com/wswind/learn-orleans/tree/master/03.MultiGrain
grain虽然是单线程的，但是我们可以创建多个grain来并行执行任务。

修改上一讲的例子：

 private static async Task DoClientWork(IClusterClient client)
        {
           
            var client1 = client.GetGrain<IHello>(0);
            var client2 = client.GetGrain<IHello>(1);

            //https://dotnet.github.io/orleans/Documentation/grains/grain_identity.html
            var id1 = client1.GetGrainIdentity().GetPrimaryKeyLong(out string keyExt);
            var id2 = client2.GetGrainIdentity().GetPrimaryKeyLong(out string keyExt2);

            Console.WriteLine(id1);
            Console.WriteLine(keyExt);
            Console.WriteLine(id2);
            Console.WriteLine(keyExt2);

            await client1.AddCount();
            var count1 = await client1.GetCount();
            Console.WriteLine("count1:{0}", count1);

            await client2.AddCount();
            await client2.AddCount();
            var count2 = await client2.GetCount();
            Console.WriteLine("count2:{0}", count2);

        }

上述代码，通过client，创建多个actor，分别执行AddCount。
可以看到各grain的状态是独立的。
