CS Prof Immanuel Trummer's paper "multi-objective parametric query optimization" has been published as Research Highlight in the October issue of Communications of the ACM. The paper connects for the first time parametric query optimization, modeling uncertainty in execution cost estimates, with multi-objective query optimization, modeling conflicting optimization goals. An approach that is "surprising in its elegance and effectiveness" according to the comment by Jeffrey Naughton.
