Optaplanner's CS-D requires that the executable model should provide a construct to build an efficient groupBy implementation.
More details are available here https://docs.google.com/document/d/1IxL2HNMNf_OYxOGGzkVjwXc7NW5ZEear-kz4OfHMXVM/edit#
We already measured that an implementation based on a 3-rules solution as sketched here https://github.com/triceo/groupby/blob/master/src/main/resources/org/optaplanner/examples/cloudbalancing/solver/cloudBalancingScoreRules3.drl fulfills the expected performance requirements, so we need
- a convenient method in the executable model DSL to define a groupBy
- an implementation that internally translates the groupBy defined with 1. into the equivalent of that 3-rules based solution
