High performance analytics with the R3cache: Datawarehouse caching using Relational OLAP,Used
Delivery time: 8-12 business days (International)
Contemporary data warehouses now represent some of the world's largest databases. As these systems grow in size and complexity, however, it becomes increasingly difficult for brute force query processing approaches to meet the performance demands of end users. In this paper, we describe the R3cache, a natively multidimensional caching framework designed specifically to support sophisticated warehouse/OLAP environments. R3cache is based upon an inmemory version of the Rtree that has been extended to support buffer pages rather than disk blocks. A key strength of the R 3cache is that it is able to utilize multidimensional fragments of previous query results so as to significantly minimize the frequency and scale of disk accesses. Moreover, the new caching model directly accommodates the standard relational storage model and provides mechanisms for proactive updates that exploit the existence of query "hot spots". The current prototype has been evaluated as a component of the Sidera DBMS, a "shared nothing" parallel OLAP server designed for multiterabyte analytics. Experimental results demonstrate significant performance improvements relative to simpler alternatives.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
