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. References

WebSep 1, 2024 · To evaluate this work, we build an in-memory storage engine, Casper, and we show that it outperforms state-of-the-art data layouts of analytical systems for hybrid workloads. Casper delivers up to 2:32 higher throughput for update-intensive workloads and up to 2:14 higher throughput for hybrid workloads.

Weboptimal con guration values of hybrid layouts based on the running workload. There are other works [2,3,11,15], which try to use di erent layouts based on the workload. The goal is always to store the data in the most appropriate one for the given workload. Yet again, they do not optimize the layouts. 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.
