ray's Introduction

Ray

This is a high-performance distributed framework that integrates Actor, Event Sourcing, and Eventual consistency (see: http://dotnet.github.io/orleans/)

Case start steps

In the case is a simple transactionless transfer function

Install (mongodb or postgresql or mysql or sqlserver) and (rabbitmq or kafka).
Select the event persistence method and EventBus in Program.cs of the Ray.Host project.

    var builder = new SiloHostBuilder()
        .UseConfiguration(config)
        .ConfigureApplicationParts(parts => parts.AddApplicationPart(typeof(Account).Assembly).WithReferences())
        .ConfigureServices((context, servicecollection) =>
        {
            //Register postgresql as an event repository
            servicecollection.AddPostgreSQLStorage(config =>
            {
                config.ConnectionDict.Add("core_event", "Server=127.0.0.1;Port=5432;Database=Ray;User Id=postgres;Password=XXXX;Pooling=true;MaxPoolSize=20;");
            });
            //Configure distributed transaction manager (not required, only need to be set if distributed transaction is required)
            servicecollection.AddPostgreSQLTxStorage(options =>
            {
                options.ConnectionKey = "core_event";
                options.TableName = "Transaction_TemporaryRecord";
            });
            servicecollection.PSQLConfigure();
        })
        .Configure<MongoConfig>(c => c.Connection = "mongodb://127.0.0.1:28888")
        .Configure<RabbitConfig>(c =>
        {
            c.UserName = "admin";
            c.Password = "XXXX";
            c.Hosts = new[] {"127.0.0.1:5672" };
            c.MaxPoolSize = 100;
            c.VirtualHost = "/";
        })
        .ConfigureLogging(logging => logging.AddConsole());

Third, modify the configuration information of Ray.Client.

    var config = ClientConfiguration.LocalhostSilo();
    var client = new ClientBuilder()
        .UseConfiguration(config)
        .ConfigureApplicationParts(parts => parts.AddApplicationPart(typeof(IAccount).Assembly).WithReferences())
        .ConfigureLogging(logging => logging.AddConsole())
        .Build();
    await client.Connect();
