Dynamic Pipelining of Multidimensional Range Queries

Amalia Duch, Daniel Lugosi, Edelmira Pasarella, Cristina Zoltan
2019 Alberto Mendelzon Workshop on Foundations of Data Management  
In this work we propose an alternative approach to evaluate multidimensional range queries based on the dynamic pipeline paradigm -using main memory and concurrency.  ...  In recent experimental works using modern hardware-with main memory and parallelism-the conclusion is that linear scan is preferable for almost every query configuration (even containing a 1% of the data  ...  Recently, multidimensional range queries as well as the efficiency of hierarchical multidimensional data structures to support them have been revisited under a modern hardware perspective [5] .  ...

Adaptive Cardinality Estimation [article]

Oleg Ivanov, Sergey Bartunov
2017 arXiv   pre-print
We consider cost-based query optimization approach as the most popular one. It was observed that cost-based optimization quality depends much on cardinality estimation quality.  ...  The execution time of different plans may differ by several orders, so query optimizer has a great influence on the whole DBMS performance.  ...  It is the only part in cost model, which depends not on hardware parameters but on data in database and clauses in the query.  ...
