“…GRFusion (HASSAN et al, 2017;HASSAN et al, 2018b;HASSAN et al, 2018a) and Db2 Graph (TIAN et al, 2019;TIAN et al, 2020) create graph views to materialize paths using customized commands and executes queries over these paths. Regarding recursive query optimizations, there are approaches for reducing its intermediary size's results (ORDONEZ, 2005); partitioning methods for the edge table (GAO et al, 2014;HONG et al, 2017;SEO;AHN;IM, 2019); specialized data representations based on adjacency lists (SUN et al, 2015;CHEN, 2013;AHMED;THOMO, 2017); in-memory graph process engines (MA et al, 2016;ZHAO et al, 2019); relational matrix algebra adaptations (DOLMATOVA; AUGSTEN; BÖHLEN, YU, 2017). The relevance of recursive queries as a field of study can be seen through several research articles (ORDONEZ; CABRERA; GURRAM, 2017;JINDAL et al, 2015;RAJ;PATEL, 2015;SIMMEN et al, 2014;PASSING et al, 2017;FLORATOS et al, 2018;ORDONEZ, 2017).…”
