Connecting Cassandra from Grain

[berataydin]

Hi,

I am trying to connect cassandra and run very simple query that returns 13 rows of data, however if I run this code from main thread (same thread that starts Silo) it works.
But when I use same code in Grain it's not working and giving some Cassandra's domain related Exception.

It's Orleans' sample tutorial-minimal code with 3 lines of Cassandra-related code, I am being sure Grain is activated, there is no any OrleansException and no any helpful info in client log nor server log.

It's very interesting I tried it with different Cassandra DB (2.1 and 3.10) and Driver versions, all same result, it's working from main thread but not working from Grain.

Any suggestion?

Thanks

But when I use same code in Grain it's not working and giving some Cassandra's domain related Exception.

Can you share more details? There's nothing particularly special about code execution within a grain other than blocking threads is bad for performance/responsiveness. Is it possible that this is an assembly loading/resolution issue?

As you see same code (ConnectionToCassandra) in host and grain, it works from host perfectly, but doesn't work from grain. It's waiting until cassandra throw timeout exception.

I digged in driver's source code, they are using task's as expected but also ConfigureAwait(false) so I am calling their methods with await as you recommend https://dotnet.github.io/orleans/Documentation/Advanced-Concepts/External-Tasks-and-Grains.html

In the grain code you do:
'return Task.FromResult(session1.Execute("select * from menu_items"));'
the 'session1.Execute' is a blocking synchronous code.
You can't do that inside the grain.
Instead you should use an async version of Execute.

If they don't have an async version, than just to test it you can try the technique with Task.Run as explained in https://dotnet.github.io/orleans/Documentation/Advanced-Concepts/External-Tasks-and-Grains.html
But this will not work well in prod (you will overload the Thread Pool). They must have an async version of this API.

[gabikliot]

you also don't need

            var orleansTaskScheduler = TaskScheduler.Current;
            Task t1 = Task.Factory.StartNew(() =>

instead:

      public async Task<RowSet> ConnectionToCassandra()
      {
              var cluster = ...;
              cluster.Configuration.SocketOptions.SetConnectTimeoutMillis(930000);
              ISession session1 = await cluster.ConnectAsync();
              return await session1.ExecuteAsync("select * from menu_items"));
      }

[berataydin]

I changed the code as below according to your feedbacks. Unfortunately it failed again.

There is no async method for cluster connect in that library and that's the line it always fails, it's never came to execute statement, always stuck on cluster connect till the timeoutexception.

public async Task<RowSet> ConnectionToCassandra()
        {
            try
            {
                var orleansTaskScheduler = TaskScheduler.Current;
                ISession session1 = await ClusterConnect();

                SimpleStatement ss = new SimpleStatement("select * from menu_items");
                return await session1.ExecuteAsync(ss);
         
            }
            catch (Exception ex)
            {

            }
            return null;
        }

        public Task<ISession> ClusterConnect()
        {
            var cluster =
                       Cluster.Builder()
                           .WithConnectionString(
                               "Contact Points=176.53.49.176;Port=9043;Default Keyspace=test_cem;UID=cassandra;PWD=cassandra;")

                           .Build();

            cluster.Configuration.SocketOptions.SetConnectTimeoutMillis(930000);

            return Task.FromResult(cluster.Connect());
        }

[berataydin]

It is fixed, it's not running with Task.Factory.StartNew but it runs with Task.Run, MSDN says Task,Run is just the lightweight version of Factory.StartNew and there is no difference between them.

So I don't understand the reason why it's running with one but not the other one.

 public Task<ISession> ClusterConnect()
        {
            //return Task.Factory.StartNew(() =>  // This fails

Task.Factory.StartNew and Task.Run are VERY different. The MSDN doc you found is probably wrong. The main difference is that Task.Run always runs on the default Scheduler, which is Thread Pool, while Task.StartNew runs on the current scheduler, which in Orleans is he Orleans scheduler.
This is the main point in the explanation in https://dotnet.github.io/orleans/Documentation/Advanced-Concepts/External-Tasks-and-Grains.html

In your case, and as explained in https://dotnet.github.io/orleans/Documentation/Advanced-Concepts/External-Tasks-and-Grains.html, the blocking call MUST be done not on the Orleans scheduler, but on the Thread Pool instead. That is, it must be done via Task.Run and not via Task.StartNew.
