Read cost (a) logarithmically decreases by adding structure (partitions), while using ghost values to expand the column layout design space (b) reduces write cost linearly w.r.t. memory amplification. - "Optimal Column Layout for Hybrid Workloads"

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 …
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. citidirect assistanceWebColumn Sketches work over column, row, and hybrid storage layouts.
