[NuGet package](https://www.nuget.org/packages/Microsoft.Orleans.EventSourcing) | [Source](https://github.com/dotnet/orleans/blob/e4e752cedecc2976811db49802c7a999b1f1c704/src/Orleans.EventSourcing/LogStorage/LogConsistencyProvider.cs#L14)

```csharp
public class LogConsistencyProvider : ILogViewAdaptorFactory
```

A log-consistency provider that stores the latest view in primary storage, using any standard storage provider. Supports multiple clusters connecting to the same primary storage (doing optimistic concurrency control via e-tags) 

The log itself is transient, i.e. not actually saved to storage - only the latest view (snapshot) and some metadata (the log position, and write flags) are stored in the primary.
