WebMay 24, 2024 · OLAP engines have been repeatedly shown to perform better if data is stored in column stores. 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 … http://daslab.seas.harvard.edu/projects/evolution/
