Column stores provide better support for data compression and are more optimized for in-memory processing of large volumes of data. Thus, the primary focus was on developing new storage layouts that can efficiently support both OLTP and OLAP … rc systems waterloo ia

"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. " - Optimal column layout for hybrid workloads
