| * Hive UDFs for Quantiles sketches. |
| * This includes UDFs for generic ItemsSketch and specialized DoublesSketch. |
| * |
| * <p>The generic implementation is in the form of abstract classes DataToItemsSketch and |
| * UnionItemsSketch to be specialized for particular types of items. |
| * An implementation for strings is provided: DataToStringsSketch, UnionStringsSketch, |
| * plus UDFs to obtain the results from sketches: |
| * GetQuantileFromStringsSketch, GetQuantilesFromStringsSketch and GetPmfFromStringsSketch. |
| * |
| * <p>Support for DoublesSketch: DataToDoublesSketch, UnionDoublesSketch, |
| * GetQuantileFromDoublesSketch, GetQuantilesFromDoublesSketch, GetPmfFromDoublesSketch |
