As an ASP.NET developer, I always wanted to have something simple to handle scenarios where you need to build a long-running async task and show a loader to a user:
Nothing is being loaded here, don't let hypnotize yourself!
But every time I faced Windows Services, message queues and other difficult-to-understand problems and hard-to-maintain solutions, my head exploded into a billion pieces. At the same time I looked at Rails’ Sidekiq and wished to have a simple .NET alternative for background job processing. That is why I began to develop Hangfire (yep, just for the loader).
Slightly more than a year passed from the first commit and first version of Hangfire. This was my first open-source project that is used more than in one organization, and it was an amazing experience for me to grow a project from scratch. I’m glad to see more and more people coming to the project and giving positive ratings and unvaluable feedback.
I want to keep Hangfire project as free as possible, but eliminate the most dangerous risk – the absence of time. There are many things to be done, including problems, new features, documentation, and I want to do them in a reasonable time.
Today, I’m introducing a new stage of Hangfire development – Hangfire Pro. It is a set of paid libraries that extend Hangfire functionality by providing features to improve performance and simplifying maintenance of background job processing in larger applications.
The Destiny of Hangfire.Redis
First, I’ll start with bad news – Hangfire.Redis package is moved to Hangfire Pro. This means that it became available only for Pro users and will be removed from public NuGet Gallery soon.
I understand that this step breaks your expectations, and I’m sorry for this. The source code will be available at Hangfire.Redis repository, but there will be no updates and official support.
Other existing parts of Hangfire will not be moved to the Pro version ever. Moreover, I’ll try to do the vice versa, by open-sourcing paid extensions in the future, when the project will be more stable.
Compatibility with ServiceStack 4.0 libraries. It still uses ServiceStack v3 libraries, but
ILMerge /internalizeutility is used to merge them into Hangfire.Redis assembly. So, you can use either Service v3 or v4 in your projects.
Configurable prefix for keys. You can use now the same database for different environments by setting corresponding prefix for keys in the
Hangfire Pro Today
Hangfire Pro already includes previously mentioned new version of Hangfire Redis package and a completely new Hangfire.PerformanceCounters package. The latter pushes internal metrics to Windows Performance Counters to proactively monitor issues with background job processing:
Hangfire Pro is available through the subscriptions you can buy at the official site. After purchasing a subscription, you will be able to do the following things:
- Access to Hangfire Pro package binaries and sources on the private GitHub repository.
- Access to priority and private support by dedicated e-mail (public forum discussions will be always free).
- Use Hangfire under EULA for organizations that don’t want to use open-source licenses.
Hangfire Pro Roadmap
As I already said, Hangfire Pro will solve performance/usability/monitoring issues for larger web applications. Further work will be made in the following directions.
Batch jobs will help to build more complex workflows with Hangfire. They will give you the power of parallel processing and continuations, you can look at this code snippet:
Three first tasks will be executed in parallel, end the continuation will be invoked only after successful run of the first tasks.
Async Methods Support
As with async controllers in ASP.NET MVC, this feature enables you to improve overall throughput keeping the lowest number of workers in the pool. Instead of waiting for an outstanding I/O operation, they will be able to process other background jobs as well.
