TOWARDS ON EXPERIMENTAL COMPARISON OF THE M-TREE INDEX STRUCTURE WITH BK-TREE AND VP-TREE [PDF]
Acta Electrotechnica et Informatica, 2020 In our previous paper, we showed the M-tree index [7] using GiST in the PostgreSQL database. In this paper, we present that result and we extend that with some preliminary experimental results with other indexes.

Graphical Join: A New Physical Join Algorithm for RDBMSs [PDF]
arXiv, 2022 Join operations (especially n-way, many-to-many joins) are known to be time- and resource-consuming. At large scales, with respect to table and join-result sizes, current state of the art approaches (including both binary-join plans which use Nested-loop/Hash/Sort-merge Join algorithms or, alternatively, worst-case optimal join algorithms (WOJAs)), may

Selectivity Estimation of Inequality Joins In Databases [PDF]
arXiv, 2022 Selectivity estimation refers to the ability of the SQL query optimizer to estimate the size of the results of a predicate in the query. It is the main calculation, based on which the optimizer can select the cheapest plan to execute. While the problem is known since the mid 70s, we were surprised that there are no solutions in the literature for the ...
