Question:
Proton CEP: How to count distinct instances in temporal context

Description:
I wish to count the number of distinct visitors to a store each half an hour.

I know I will need:

the temporal context (half an hour)

What kind of EPA should I create to count distinct visitor ids?

I suppose I will need an internal segmentation by visitorId?
