Optimal column layout for hybrid workloads

WebTitle: Optimal Column Layout for Hybrid Workloads Data-intensive analytical applications need to support both efficient reads and writes. However, what is usually a good data layout for an update-heavy workload, is not well-suited for a read-mostly one and vice versa. WebApproach #1: Perform Extra Reads →Execute two reads to load the appropriate parts of the data word and reassemble them. Approach #2: Random Reads →Read some unexpected …

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. 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.
