generalized concepts for grouping and aggregation. While, in its current form, this paradigm is limited to equality based grouping and restricted aggregate functions, it can be a powerful operation if extended to support more complex intra-group relationships and advanced aggregate functions. ...

In case you group values by key, it's not possible to utilize map side aggregation (combiner) like in groupbykey operation. This is because all values for each key should be present after the completion of groupByKey operation. Therefore, local reduction of values (combiner) cannot be performed...
in the database, each result criterion corresponding to a logical field for which data is to be returned; receiving user input specifying selection criteria for the abstract query; receiving user input specifying an aggregation operation to be performed with respect to the at least one result ...
The group-by and aggregation are fundamental but time-consuming operations for a DBMS. Using hash tables is a common approach to perform a grouping. In this paper, we study how to utilize the heterogeneous CPU-GPU platform to accelerate the group-by and aggregation based on the chained ...
