Instance-Optimized Data Layouts for Cloud Analytics Workloads
Summary: Introducing MTO, an instance-optimized data-layout framework that jointly blocks across all tables in multi-table cloud workloads (star/snowflake schemas) to maximize block skipping. Leveraging sideways information from joins, it beats single-table layouts, with up to 93% fewer blocks accessed and 75% faster end-to-end queries on a commercial service.
