Microsoft Orleans Journaling for Azure Storage

Introduction

Microsoft Orleans Journaling for Azure Storage provides an Azure Storage implementation of the Orleans Journaling provider. This allows logging and tracking of grain operations using Azure Storage as a backing store.

Getting Started

To use this package, install it via NuGet:

dotnet add package Microsoft.Orleans.Journaling.AzureStorage

Example - Configuring Azure Storage Journaling

using Microsoft.Extensions.Hosting;
using Orleans.Hosting;
using Orleans.Configuration;
using System;
using System.Threading.Tasks;
using Microsoft.Extensions.DependencyInjection;
using MyGrainNamespace;

var builder = Host.CreateApplicationBuilder(args)
    .UseOrleans(siloBuilder =>
    {
        siloBuilder
            .UseLocalhostClustering()
            // Configure Azure Storage as a journaling provider
            .AddAzureAppendBlobStateMachineStorage(optionsBuilder =>
            {
                optionsBuilder.Configure((options, serviceProvider) => options.BlobServiceClient = serviceProvider.GetRequiredService<BlobServiceClient>());
            });
    });

var host = await builder.StartAsync();

// Get a reference to the grain
var shoppingCart = host.Services.GetRequiredService<IGrainFactory>()
    .GetGrain<IShoppingCartGrain>("user1-cart");

// Use the grain
await shoppingCart.UpdateItem("apple", 5, 0);
await shoppingCart.UpdateItem("banana", 3, 1);

// Get and print the cart contents
var (contents, version) = await shoppingCart.GetCart();
Console.WriteLine($"Shopping cart (version {version}):");
foreach (var item in contents)
{
    Console.WriteLine($"- {item.Key}: {item.Value}");
}

// Wait for the application to terminate
await host.WaitForShutdownAsync();

Example - Using Journaling in a Grain

using Orleans.Runtime;

namespace MyGrainNamespace;

public interface IShoppingCartGrain : IGrain
{
    ValueTask<(bool success, long version)> UpdateItem(string itemId, int quantity, long version);
    ValueTask<(Dictionary<string, int> Contents, long Version)> GetCart();
    ValueTask<long> GetVersion();
    ValueTask<(bool success, long version)> Clear(long version);
}

public class ShoppingCartGrain(
    [FromKeyedServices("shopping-cart")] IDurableDictionary cart,
    [FromKeyedServices("version")] IDurableValue<long> version) : DurableGrain, IShoppingCartGrain
{
    private readonly IDurableValue<long> _version = version;

    public async ValueTask<(bool success, long version)> UpdateItem(string itemId, int quantity, long version)
    {
        if (_version.Value != version)
        {
            // Conflict
            return (false, _version.Value);
        }

        if (quantity == 0)
        {
            cart.Remove(itemId);
        }
        else
        {
            cart[itemId] = quantity;
        }

        _version.Value++;
        await WriteStateAsync();
        return (true, _version.Value);
    }

    public ValueTask<(Dictionary<string, int> Contents, long Version)> GetCart() => new((cart.ToDictionary(), _version.Value));
    public ValueTask<long> GetVersion() => new(_version.Value);

    public async ValueTask<(bool success, long version)> Clear(long version)
    {
        if (_version.Value != version)
        {
            // Conflict
            return (false, _version.Value);
        }

        cart.Clear();
        _version.Value++;
        await WriteStateAsync();
        return (true, _version.Value);
    }
}
