Description

In rel/0.13, the computation of a RowRecord in GroupByWithoutValueFilterDataSet is a single thread process. In case the aggregation result cotaining hundreds of columns, the time for these computation is much long (in my PC, about 10.8 seconds), so I use multi thread strategy to speed up the computation.
