Configuring Job Queues

Configuring Job Queues — Hangfire Documentation

Hangfire can process multiple queues. If you want to prioritize your jobs, or split the processing across your servers (some processes for the archive queue, others for the images queue, etc), you can tell Hangfire about your decisions.

https://docs.hangfire.io/en/latest/background-processing/configuring-queues.html

You can force background workers to only subscribe to tasks with a specified queue name.

Client

[Queue("alpha")]
public void SomeMethod() { }

BackgroundJob.Enqueue(() => SomeMethod());

Background Worker

Note: the lower the index of the queue name will have the higher priority in processing order

public void ConfigureServices(IServiceCollection services)
{
    // Add the processing server as IHostedService
    services.AddHangfireServer(options =>
    {
        options.Queues = new[] { "alpha", "beta", "default" };
    });
}
