Optimal column layout for hybrid workloads
WebSep 1, 2024 · Modern analytical data systems rely on columnar layouts and employ delta stores to inject new data and updates. We show that for hybrid workloads we can achieve close to one order of magnitude better performance by tailoring the column layout design to the data and query workload. http://daslab.seas.harvard.edu/projects/evolution/

WebIn this paper, we propose MTO, an instance-optimized data layout framework that determines the blocking strategy for all tables in a multi-table database in the presence of joins, such as in a star or snowflake schema common in real-world workloads.
WebJun 14, 2016 · Our results show that our approach delivers up to 3x higher throughput compared to static storage layouts across different workloads. We also demonstrate that our continuous adaptation mechanism allows the DBMS to achieve a near-optimal layout for an arbitrary workload without requiring any manual tuning.

WebFigure 2: Accessing a column is heavily affected by the structure of the column (e.g., sorted, partitioned). Read cost (a) logarithmically decreases by adding structure (partitions), while using ghost values to expand the column layout design space (b) reduces write cost linearly w.r.t. memory amplification. - "Optimal Column Layout for Hybrid Workloads"
