Session title: Db2 Columnar Architecture (including 11.5 enhancements)
Session abstract: We will start with a high-level introduction into the columnar format: from how are columns split up to pages and extents to answering basic questions like what is a synopsis table. Next up is compression –topics include encoding, dictionaries, and grooming — and how v11.1 and 11.5 compare and contrast. Finally we’ve move to MPP and WLM both topics that can be key in analytic workloads. Throughout this presentation, new functionality in 11.5 will be highlighted. As we close, we will include some details on potential items in the V11.5 continuous delivery roadmap.
