%X Data distribution is a challenge in the distributed execution of multiway spatial join queries. An efficient execution requires both a balanced data distribution as well as a distribution with spatial data colocalization. In this paper, we compare two methods of spatial data distribution and propose a new one called Gain-Loss, based in the R0-tree algorithms. Our evaluation shows that Gain-Loss has a reduced area overlay between servers in all tested scenarios and also a competitive object balancing. This result indicates a more efficient execution of queries, with a reduction in the use of computational resources, mainly network usage and processing time.
