Abstract: Since 2013, dynamic programming (DP)-based plan generators are capable of correctly reordering not only inner joins, but also outer joins. Now, we consider the next big step: reordering not only joins, but also joins and grouping. Since only reorderings of grouping with inner joins are known, we first develop equivalences which allow reordering of grouping with outer joins. Then, we show how to extend a state-of-the-art DP-based plan generator to fully explore these new plan alternatives.
