MeshWeaver.Hosting.Orleans
Overview
MeshWeaver.Hosting.Orleans provides a distributed hosting model for MeshWeaver using Microsoft Orleans. Each message hub is represented as a virtual actor (grain) in the Orleans cluster, enabling automatic distribution, scalability, and fault tolerance.
How It Works
- Each message hub is mapped to an Orleans grain
- Messages are dispatched through Orleans silos
- Grains are automatically distributed across the cluster
- Virtual actor model ensures hubs are always addressable
- Orleans handles activation/deactivation and placement of hubs
Usage
var builder = WebApplication.CreateBuilder(args);
// Configure Orleans cluster
builder.Host.UseOrleans(orleans =>
{
orleans.UseLocalhostClustering();
// Configure other Orleans options
});
// Configure MeshWeaver with Orleans hosting
builder.UseMeshWeaver(
new MeshAddress(),
config => config
.ConfigureWebPortal()
.ConfigurePortalMesh()
.UseOrleansMesh()
.ConfigureServices(services => services.AddArticles())
);
var app = builder.Build();
app.StartPortalApplication();
