[NuGet package](https://www.nuget.org/packages/Microsoft.Orleans.Streaming) | [Source](https://github.com/dotnet/orleans/blob/e4e752cedecc2976811db49802c7a999b1f1c704/src/Orleans.Streaming/QueueBalancer/DeploymentBasedQueueBalancer.cs#L22)

```csharp
public class DeploymentBasedQueueBalancer : QueueBalancerBase, IStreamQueueBalancer
```

DeploymentBasedQueueBalancer is a stream queue balancer that uses deployment information to help balance queue distribution. DeploymentBasedQueueBalancer uses the deployment configuration to determine how many silos to expect and uses a silo status oracle to determine which of the silos are available. With this information it tries to balance the queues using a best fit resource balancing algorithm.
