Session title: Db2 Turbo Statistics – How to Accelerate Your Query Performance
Session abstract: Catalog statistics are what fuel the Db2 optimizer, and its tank is always full because of automatic statistics collection. However there are some extra buttons on the dashboard that you can use to enable even better statistics to really boost your query performance.
Statistical views are an advanced form of statistics that allow the optimizer to see relationships across joins and to see the data distributions for expressions and even groups of expressions. Statistical views can be combined with column groups and distribution statistics to provide a high-octane boost to your queries with the added benefit of more stable and reliable query performance. Attend this presentation to learn how to use these more advanced forms of statistics to get top performance out of your Db2 system.
