NServiceBus.MongoDB

MongoDB persistence for NServicBus 5.x

Installation

• Get the source and build locally

or

• Install the NServiceBus.MongoDB NuGet package using the Visual Studio NuGet Package Manager

Configuration

After adding a reference to it from your project, specify MongoDBPersistence to be used for persistence.

using NServiceBus;
using NServiceBus.MongoDB;

public class EndpointConfig : IConfigureThisEndpoint, AsA_Server
{
  public void Customize(BusConfiguration configuration)
  {
    configuration.UsePersistence<MongoDBPersistence>()
        .SetDatabaseName("MyDatabase");
  }
}

This base configuration connects using NServiceBus/Persistence/MongoDB connection string in the app.config and MyDatabase as the database.

<connectionStrings>
  <add name="NServiceBus/Persistence/MongoDB" connectionString="mongodb://localhost:27017" />
</connectionStrings>

If this connection string is not found NServiceBus/Persistence is used.

<connectionStrings>
  <add name="NServiceBus/Persistence" connectionString="mongodb://localhost:27017" />
</connectionStrings>

or specify the connection string to use:

using NServiceBus;
using NServiceBus.MongoDB;

public class EndpointConfig : IConfigureThisEndpoint, AsA_Server
{
  public void Customize(BusConfiguration configuration)
  {
    configuration.UsePersistence<MongoDBPersistence>()
        .SetConnectionString("mongodb://localhost:27017")
        .SetDatabaseName("MyDatabase");
  }
}

DataBus Configuration

To configure NServiceBus to use MongoDB GridFS as the persistence for DataBus use the following configuration.

using NServiceBus;
using NServiceBus.MongoDB;

public class EndpointConfig : IConfigureThisEndpoint, AsA_Server
{
  public void Customize(BusConfiguration configuration)
  {
    configuration.UsePersistence<MongoDBPersistence>();
    configuration.UseDataBus<MongoDBDataBus>();
  }
}

Sagas

Saga data needs to be defined the normal way NSB requires with the additional interface IHaveDocumentVersion to work appropriately with NServiceBus.MongoDB. All this interface adds is a version property. Alternatively you can just inherit from ContainMongoSagaData as follows:

using NServiceBus.MongoDB;
using NServiceBus.Saga;

public class MySagaData : ContainMongoSagaData
{
    [Unique]
    public string SomeId { get; set; }

    public int Count { get; set; }
}
