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.
