  17. Raw data aggregation • Well optimized storage • Partitioned table • No global indexes (including the PK) Alexandre Beche – White Area

  18. Raw data aggregation • Well optimized storage • Partitioned table • No global indexes (including the PK) • Aggregation of unordered events • Stateless: Full re-computation of touched bins each time • Compute stats from raw data in 10 min bins • Aggregate 10 min stats in daily bins Alexandre Beche – White Area
