> A first support for GROUPING SETS has been added in FLINK-5303. However, the current runtime implementation is not very efficient as it basically only translates logical operators to physical operators i.e. grouping sets are currently only translated into multiple groupings that are unioned together. A rough design document for this has been created in FLINK-2980.
