          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?
