Parallel Query Support for Multidimensional Data: Inter-object Parallelism [chapter]

Karl Hahn, Bernd Reiner, Gabriele Höfling, Peter Baumann
2002 Lecture Notes in Computer Science  
This paper presents a number of new techniques for parallelizing queries in multidimensional array database management systems.  ...  However, the methods have yet not been applied to the upcoming field of multidimensional array databases. Specific properties of multidimensional array data require new parallel algorithms.  ...  In order to achieve performance improvements for a query which executes array operations on a single MDD, the concept described here is not suitable, as the granularity of our data parallelism is a complete  ...

Yansong Zhang, Xuan Zhou, Ying Zhang, Yu Zhang, Mingchuan Su, Shan Wang
2016 IEEE Transactions on Knowledge and Data Engineering  
As a result, this tactic is rarely used in main memory databases, which regards storage space, i.e., RAM, as scarce resource.  ...  It applies a number of state-of-the-art optimization methods, such as vectorized scan and aggregation, to achieve superior performance.  ...  According to our evaluation, the multidimensional array of most OLAP queries in SSB, TPC-H and TPC-DS is smaller than an ordinary LLC.  ...
