This is a StorageProvider for RavenDB for the Microsoft Research Project Orleans. The storage provider allows to persist stateful grains into RavenDB. The provider offers the following options:
In order to use the provider you need to add the following provider to your configuration:
<Provider Type="Orleans.StorageProvider.RavenDB.RavenDBStorageProvider" Name="RavenDBStore" ConnectionStringName="RavenDB"/>
and this line to any grain that uses it
[StorageProvider(ProviderName = "RavenDBStore")]
In addition you need an application configuration file (app.config) with a connection string named after the ConnectionStringName in the provider configuration entry.
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<connectionStrings>
<add name="RavenDB" connectionString="YOUR CONNECTION STRING HERE"/>
</connectionStrings>
</configuration>
All connection string officially supported by RavenDB are also supported by the provider. The mode (Server, Embedded, InMemory) is chosen based on the connection string according to the following strategy:
Here are examples of such connection strings:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<connectionStrings>
<add name="RavenDB" connectionString="Url = http://localhost:8080;Database=RavenDBStorageProviderTests"/> <!-- Server Mode -->
<add name="RavenDBLocal" connectionString="DataDir = ~\Data"/> <!-- Embedded Mode -->
</connectionStrings>
</configuration>
<Provider Type="Orleans.StorageProvider.RavenDB.RavenDBStorageProvider" Name="RavenDBStore" ConnectionStringName=""/> <!-- InMemory Mode -->
