Event Prioritization #5535

Open Spenhouet opened 3 years ago

Spenhouet commented 3 years ago

Problem Given many events of the same type but for example for different groups. The group could be anything provided by the event producer e.g. a customer.

In our specific use-case we are limited by hardware resources (GPUs specifically). There might be 1000 requests by group 1 and only 10 requests by group 2. We would like the ability to apply some fairness factor so that group 2 will be scheduled with a higher priority than group 1.

Additional context (optional)

I'm not sure if something like this already exists. Kubernetes seems to have something in this direction: Pod Priority and Preemption If this does not exist yet, then I would like to make this a feature request.

It is also open where the interface for this is. Such a fairness factor could be automatically calculated and managed by Knative but could also just be provided by the event producer.
