Is your feature request related to a problem? Please describe.
Currently feedback must be unique of user_id,item_id,feedback_type. In our usecase we would like the model to take in to account the number of times the feedback was provided. eg: If an item was viewed multiple times.

Describe the solution you'd like
A clear and concise description of what you want to happen.
Multiple triads of user_id,item_id,feedback_type can be inserted as feedback.

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

• Multiple 'sub' feedback types eg 'viewed-1', 'viewed-2'

There is two way to achieve this:

1. Support duplicate feedback
2. Add a count field into feedback.

I prefer the second one. Do you think the second one meets your situation?

In the case of solution 2 I don't immediately see how a feedback TTL can be implemented.
It seems cleaner to have 1 row per feedback instance and have the existing TTL logic apply.

Having some sort of visibility into when feedback was given may also improve the recommendations

To be honest, the first one is easier to implement 😂 This feature is not easy to implement, it might be implemented several versions latter

Can you shed some light on to where the complexity lies? I would love to improve my understanding of this problem !
