Usage Pattern-Driven Dynamic Data Layout Reorganization

Tang, H., Byna, S., Harenberg, S., Zou, X., Zhang, W., Wu, K., … Samatova, N. F. (2016, May 1).

By: H. Tang n, S. Byna *, S. Harenberg n, X. Zou n, W. Zhang n, K. Wu *, B. Dong *, O. Rubel * ...

topics (OpenAlex): Advanced Data Storage Technologies; Parallel Computing and Optimization Techniques; Advanced Database Systems and Queries
TL;DR: This work proposes a framework that dynamically recognizes the data usage patterns, replicates the data of interest in multiple reorganized layouts that would benefit common read patterns, and makes runtime decisions on selecting a favorable layout for a given read pattern.
