          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?

            Here you go:

            • The EPA should be of type Aggregate.
            • Yes, you need internal segmentation context by visitorId.

            See the documentation for a sample which demonstrates how to perform count:
            https://github.com/ishkin/Proton/tree/master/documentation/sample/fraud
            A pdf doc included.

            Hope this help.
