Optimizing OLAP cube processing on solid state drives

Content Provider ACM Digital Library
Author Chen, Zhibo Ordonez, Carlos
Abstract Hardware technology has improved to a point where a solid state drive (SSD) can read faster than a traditional hard disk drive (HDD). This unique ability to retrieve data quickly combines perfectly with OLAP cube processing. In this paper, we study how to improve performance of OLAP cube processing on SSDs. The main novelty of our work is that we do not alter the internal subsystems of the DBMS. Instead, the DBMS treats the SSD as though it was a regular HDD. We propose optimizations for SQL queries to enhance their performance on SSDs. An experimental evaluation with the TPC-H database compares performance of our optimizations on SSDs and HDDs. We found that even though SSDs have slower write speeds than HDDs, their excellent read speed more than overcomes this limitation.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
