这是一个集成Actor,Event Sourcing,Eventual consistency的高性能分布式框架(构建分布式集群请参阅:http://dotnet.github.io/orleans/)
案例里是一个简单的无事务转账功能
一、安装(mongodb or postgresql or mysql or sqlserver) and (rabbitmq or kafka)。
二、在Ray.Host项目的Program.cs中选择事件持久化方式和EventBus。
var builder = new SiloHostBuilder()
.UseConfiguration(config)
.ConfigureApplicationParts(parts => parts.AddApplicationPart(typeof(Account).Assembly).WithReferences())
.ConfigureServices((context, servicecollection) =>
{
//注册postgresql为事件存储库
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;");
});
//配置分布式事务管理器(非必须，需要分布式事务才需设置)
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());三、修改Ray.Client的配置信息.
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();四、启动Ray.Host
五、启动Ray.Client
