Service Fabric sample: Reliable Collection Query

Service Fabric currently doesn't provide a way to browse the data in reliable collections. This sample provides a way to get reliable collection data as JSON and dump them into files. You can use the same interface to build a web app that allows browsing collection data (just be sure to secure it properly).

The project contains a simple implementation of this interface for any stateful reliable service:

public interface IReliableServiceQuery : IService
{
    Task<IList<Uri>> GetCollections();
    Task<IList<string>> GetCollectionData(Uri name);
}

Note that it currently uses Reflection with non-public APIs since ReliableStateManager.GetEnumerator() currently throws a NotImplementedException.

There is also a project called ReliableCollectionDump that can run on the cluster's VM and dump entire collections into JSON files. For each partition, a file is created with the name AppName_ServiceName_PartitionId.json. The output looks like this:
