How to Set Retry Count to 0 by Default for All Hangfire Jobs

If you are utilizing Hangfire in your C# ASP.NET Core 3.1 application for scheduling background jobs, you may have encountered the default setting for automatic retries. By default, Hangfire attempts to retry a job that fails up to 10 times before it considers that job as permanently failed. This can lead to unnecessary processing and delay, especially if you have a large number of jobs. Fortunately, you can customize this behavior.

In this guide, we'll explore how you can set the default retry count to 0 for all Hangfire jobs, so you won’t have to specify it individually within each job. This approach improves clarity in job management and saves a lot of time.

Understanding the Default Behavior

Before diving into the solution, it's essential to understand what the default behavior of Hangfire is:

Retry Attempts: When a background job fails, Hangfire will retry it 10 times by default.

AutomaticRetry Attribute: While you can change the retry count using the AutomaticRetry attribute for individual jobs, it can become cumbersome to apply this on every job decorator when you want the majority to have a retry count of 0.

Solution: Setting the Default Retry Count to 0

To set the default retry count to 0 for all Hangfire jobs, you can conveniently modify the global job filters. This setting will ensure that all jobs will not have any retries unless specified otherwise.

Step-by-Step Implementation

Access Your Startup Configuration
In your ASP.NET Core application, locate the Startup.cs file. This file is where many of your application's configurations are handled.

Modify Job Filters
You will need to add a global job filter in the ConfigureServices method. Use the following code snippet to achieve this:

Code Example

Here’s how the modification would appear within the Startup.cs file:

Explanation of the Code

GlobalJobFilters: This allows you to add a filter that affects all jobs processed by Hangfire.

AutomaticRetryAttribute: This class allows you to set the number of retry attempts for failed jobs. By specifying Attempts = 0, you are effectively disabling retries for all jobs.

Exceptional Cases: Specifying Non-Zero Retries

If, in some rare cases, you want to allow for retries on specific jobs, you can still use the AutomaticRetry attribute directly on those jobs without any conflict. It would look like:

Conclusion

Setting the default retry count to 0 for all Hangfire jobs is a straightforward process that significantly simplifies job management in your ASP.NET Core application. By implementing this global filter, you not only streamline your error handling but also enhance the overall performance of your background processing.

Now, you can handle exceptions in a way that aligns with your project requirements without getting bogged down by unnecessary retries. As always, remember to test thoroughly to ensure this adjustment meets your application’s needs.
