- From a technical point of view, the result of the map query is uploaded to the KIK-Starter centraal and the reduce query is executed on the centraal to extract information when needed. This means that only the results of the query (in the sense of the map query) is uploaded, not the detailed data. Splitting the two allows doing more sophisticated aggregation at the central if needed.
