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. WebJun 26, 2016 · Our results show that our approach delivers up to 3x higher throughput compared to static storage layouts across different workloads.
