This talk describes how Avito implemented traffic analytics (unique visitors and sessions) on HP Vertica. It explains the challenge that unique counts are non-additive across hierarchical dimensions (like geography or product categories) and how they built a MapReduce-style solution on top of Vertica’s SQL engine to compute detailed, accurate, ad-hoc reports over tens of billions of rows.
