Query Rewriting via LLMs
Sriram Dharwada, Himanshu Devrani, Jayant Haritsa +1
When complex SQL queries suffer slow executions despite query optimization, DBAs typically invoke automated query rewriting tools to recommend ``lean'' equivalents that are conduci…
GPU-Powered Spatial Database Engine for Commodity Hardware: Extended Version
Harish Doraiswamy, Juliana Freire
Given the massive growth in the volume of spatial data, there is a great need for systems that can efficiently evaluate spatial queries over large data sets. These queries are noto…
The Case for Distance-Bounded Spatial Approximations
Eleni Tzirita Zacharatou, Andreas Kipf, Ibrahim Sabek +3
Spatial approximations have been traditionally used in spatial databases to accelerate the processing of complex geometric operations. However, approximations are typically only us…
A GPU-friendly Geometric Data Model and Algebra for Spatial Queries: Extended Version
Harish Doraiswamy, Juliana Freire
The availability of low cost sensors has led to an unprecedented growth in the volume of spatial data. However, the time required to evaluate even simple spatial queries over large…
