Zel*_*tor 5 sql-server provider orleans
我正在尝试将SQL Server用作Orleans的数据存储.
我已设法使用Azure本地存储模拟器使我的解决方案正常工作,但无法使其与SQL Server的本地实例一起使用.我使用以下方法创建了数据库:
https://github.com/dotnet/orleans/blob/master/src/OrleansSQLUtils/CreateOrleansTables_SqlServer.sql
并使我的配置文件看起来像这里的那个:
http://dotnet.github.io/orleans/Documentation/Advanced-Concepts/Configuring-SQL-Tables.html
这是我的配置文件:
<?xml version="1.0" encoding="utf-8"?>
<OrleansConfiguration xmlns="urn:orleans">
<Globals>
<StorageProviders>
<SystemStore SystemStoreType ="SqlServer"
DeploymentId="OrleansTest"
DataConnectionString="Data Source=.\SQL2014;Initial Catalog=Orleans;Integrated Security=True;Pooling=False;Max Pool Size=200;Asynchronous Processing=True;MultipleActiveResultSets=True" AdoInvariant="System.Data.SqlClient" />
<Provider Type="Orleans.SqlUtils.StorageProvider.SqlStorageProvider" Name="SqlServer" />
<!--<Provider Type="Orleans.Storage.AzureTableStorage" Name="AzureStore" DataConnectionString="UseDevelopmentStorage=true" />-->
</StorageProviders>
<SeedNode Address="localhost" Port="11111" />
</Globals>
<Defaults>
<Networking Address="localhost" Port="11111" />
<ProxyingGateway Address="localhost" Port="30000" />
</Defaults>
</OrleansConfiguration>

我在谷物中添加了以下属性:
[StorageProvider(ProviderName = "SqlServer")]

然后我得到以下错误:
Could not locate a state map factory type...
请有人让我知道我需要添加到提供商或我是否做了其他错误的事情?我是否需要为SQL提供程序创建与StateMapFactoryType有关的内容?
谢谢
首先,这<SystemStore>不是 StorageProvider。该节点用于成员资格预言机。像这样:
<OrleansConfiguration xmlns="urn:orleans">
<Globals>
<SystemStore SystemStoreType ="SqlServer"
DeploymentId="OrleansTest"
DataConnectionString="Data Source=.\SQL2014;Initial Catalog=Orleans;Integrated Security=True;Pooling=False;Max Pool Size=200;Asynchronous Processing=True;MultipleActiveResultSets=True" AdoInvariant="System.Data.SqlClient" />
</Globals>
<Defaults>
<Networking Address="" Port="11111" />
<ProxyingGateway Address="" Port="30000" />
</Defaults>
</OrleansConfiguration>

现在让我们输入您的 StorageProvider
<OrleansConfiguration xmlns="urn:orleans">
<Globals>
<StorageProviders>
<Provider Type="Orleans.SqlUtils.StorageProvider.SqlStorageProvider" Name="SqlServer" />
</StorageProviders>
<SystemStore SystemStoreType ="SqlServer"
DeploymentId="OrleansTest"
DataConnectionString="Data Source=.\SQL2014;Initial Catalog=Orleans;Integrated Security=True;Pooling=False;Max Pool Size=200;Asynchronous Processing=True;MultipleActiveResultSets=True" AdoInvariant="System.Data.SqlClient" />
</Globals>
<Defaults>
<Networking Address="" Port="11111" />
<ProxyingGateway Address="" Port="30000" />
</Defaults>
</OrleansConfiguration>

现在到有趣的部分了。设置Orleans.SqlUtils.StorageProvider.SqlStorageProvider
这个特定的存储提供程序基于 P&P 集团的 ElasticClient,它使用特殊的分片数据库(例如分片主数据库和分片数据库)
可能会建议这个较低摩擦的提供程序(插入无耻的插件(如果它有效,我写了它,如果它不起作用,那么我不知道是谁做的:D)https://github.com/OrleansContrib/Orleans.StorageProviders.SimpleSQLServerStorage
ok,回到Orleans.SqlUtils.StorageProvider.SqlStorageProvider
你还需要几个配置项:
<Provider Type="Orleans.SqlUtils.StorageProvider.SqlStorageProvider" Name="guts" ConnectionString = "Server=.;Initial catalog=guts;Integrated Security=SSPI;" MapName="guts" StateMapFactoryType="ClassName, assemblyname" />

您需要创建 StateMapFactory 实现,Orleans.SqlUtils.StorageProvider.IGrainStateMapFactory
请参阅
https://github.com/dotnet/orleans/blob/v1.1.3/src/OrleansSQLUtils/Storage/Provider/IGrainStateMapFactory.cs
但!!看起来版本 1.1.3 仍然标记Orleans.SqlUtils.StorageProvider.IGrainStateMapFactory为内部,因此您必须从源代码编译或从 github 获取最新版本。
