Microsoft.Orleans.Clustering.AzureStorage 9.2.0-preview3

Microsoft Orleans Clustering Provider for Azure Storage

Introduction

Microsoft Orleans Clustering Provider for Azure Storage allows Orleans silos to organize themselves as a cluster using Azure Table Storage. This provider enables silos to discover each other, maintain cluster membership, and detect and handle failures.

Getting Started

To use this package, install it via NuGet:

dotnet add package Microsoft.Orleans.Clustering.AzureStorage

Example - Configuring Azure Storage Clustering

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

// Define a grain interface
public interface IHelloGrain : IGrainWithStringKey
{
    Task<string> SayHello(string greeting);
}

// Implement the grain interface
public class HelloGrain : Grain, IHelloGrain
{
    public Task<string> SayHello(string greeting)
    {
        return Task.FromResult($"Hello, {greeting}!");
    }
}

var builder = Host.CreateApplicationBuilder(args)
    .UseOrleans(siloBuilder =>
    {
        siloBuilder
            // Configure Azure Table Storage for clustering
            .UseAzureStorageClustering(options =>
            {
                options.ConnectionString = "YOUR_AZURE_STORAGE_CONNECTION_STRING";
                options.TableName = "OrleansClustering"; // Optional: defaults to "OrleansClustering"
            });
    });

var host = builder.Build();
await host.StartAsync();

// Get a reference to a grain and call it
var client = host.Services.GetRequiredService<IClusterClient>();
var grain = client.GetGrain<IHelloGrain>("user123");
var response = await grain.SayHello("World");

// Print the result
Console.WriteLine($"Grain response: {response}");

// Keep the host running until the application is shut down
await host.WaitForShutdownAsync();

Example - Configuring Client to Connect to Cluster

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

// Define a grain interface
public interface IHelloGrain : IGrainWithStringKey
{
    Task<string> SayHello(string greeting);
}

var clientBuilder = Host.CreateApplicationBuilder(args)
    .UseOrleansClient(clientBuilder =>
    {
        clientBuilder
            // Configure the client to use Azure Storage for clustering
            .UseAzureStorageClustering(options =>
            {
                options.ConnectionString = "YOUR_AZURE_STORAGE_CONNECTION_STRING";
                options.TableName = "OrleansClustering"; // Optional: defaults to "OrleansClustering"
            });
    });

var host = clientBuilder.Build();
await host.StartAsync();
var client = host.Services.GetRequiredService<IClusterClient>();

// Get a reference to a grain and call it
var grain = client.GetGrain<IHelloGrain>("user123");
var response = await grain.SayHello("World");

// Print the result
Console.WriteLine($"Grain response: {response}");

// Keep the host running until the application is shut down
await host.WaitForShutdownAsync();
