Abstract:We consider data-visualization systems where data is stored in a database, and a middleware layer translates a frontend request to a SQL query to the database to compute visual results. We focus on the problem of handling visualization requests with predetermined time constraints. We study how to rewrite the original query by adding hints and/or conducting approximations so that the total time is within the time constraint. We develop a novel middleware solution called Maliva, which adopts machine learning (ML… Show more
