Should a work queue retry business exceptions?

When it comes to handling exceptions in work queues, it's important to understand the distinctions between business and system exceptions. Business exceptions are typically related to specific business rules or conditions, such as incorrect data or failed validation processes, whereas system exceptions are generally caused by technical issues like network outages or application failures.

The most appropriate approach regarding whether a work queue should retry business exceptions is to recognize that these exceptions often indicate a fundamental issue that cannot be resolved simply by retrying the same process. Re-attempting a business exception without addressing the underlying cause might lead to repeated failures, resulting in inefficiencies and wasted resources.

Consequently, the best practice is to focus on system exceptions for retries. These exceptions may indeed be transient problems that could succeed on subsequent attempts. Thus, while a work queue may be configured to handle retries for system exceptions, it should not automatically retry business exceptions. This approach ensures that the root cause of any business-related issues is addressed appropriately, rather than masking them with repeated attempts.
