Here is what we do for each level:

+ *
  • If it does not need to be compacted, then simply copy it over.
    • + *
  • Otherwise, it does need to be compacted, so... + *
    • Copy zero or one guy over.
      • + *
    • If the level above is empty, halve up.
      • + *
    • Else the level above is nonempty, so halve down, then merge up.
      • + *
    • + *
  • Adjust the boundaries of the level above.
    • + *
+ * + *

It can be proved that generalCompress returns a sketch that satisfies the space constraints + * no matter how much data is passed in. + * We are pretty sure that it works correctly when inBuf and outBuf are the same. + * All levels except for level zero must be sorted before calling this, and will still be + * sorted afterwards. + * Level zero is not required to be sorted before, and may not be sorted afterwards.

+ * + *

This trashes inBuf and inLevels and modifies outBuf and outLevels.

In the main code, nearly all the corrections are in the Javadocs. However, in the test code, there were many places where he was comparing a long vs a float ('cause he copied the code from the float classes). Also, he didn't check the test classes with printing enabled. There were numerous places where the printf format expected an "%f" that should have been a "%d". Nonetheless, Zac did an amazing job of creating this KllLongsSketch, considering the complexity of the code! I also did a coverage tests and made sure that the coverage of the "longs" classes were very close to the coverage of the comparable "doubles" and "floats" classes -- and they were! This means that he was able to faithfully translate all the relevant tests from float to longs and I did not find any gaps in testing. --- .../kll/KllDirectLongsSketch.java | 41 +- .../datasketches/kll/KllHeapLongsSketch.java | 27 +- .../apache/datasketches/kll/KllHelper.java | 14 +- .../datasketches/kll/KllLongsHelper.java | 36 +- .../datasketches/kll/KllLongsSketch.java | 1115 +++++++++-------- .../datasketches/kll/KllPreambleUtil.java | 5 +- .../apache/datasketches/kll/KllSketch.java | 5 +- .../quantilescommon/DoublesSortedView.java | 5 +- .../LongsSketchSortedView.java | 8 +- .../quantilescommon/LongsSortedView.java | 12 +- .../quantilescommon/QuantilesLongsAPI.java | 496 ++++---- .../quantilescommon/QuantilesUtil.java | 4 +- .../kll/KllDirectCompactLongsSketchTest.java | 48 +- .../kll/KllDirectLongsSketchIteratorTest.java | 15 +- .../kll/KllDoublesSketchSerDeTest.java | 12 +- .../kll/KllLongsSketchSerDeTest.java | 30 +- .../datasketches/kll/KllLongsSketchTest.java | 86 +- .../kll/KllMiscDirectLongsTest.java | 78 +- .../datasketches/kll/KllMiscLongsTest.java | 50 +- 19 files changed, 1080 insertions(+), 1007 deletions(-) diff --git a/src/main/java/org/apache/datasketches/kll/KllDirectLongsSketch.java b/src/main/java/org/apache/datasketches/kll/KllDirectLongsSketch.java index a3edf319b..bf91baabd 100644 --- a/src/main/java/org/apache/datasketches/kll/KllDirectLongsSketch.java +++ b/src/main/java/org/apache/datasketches/kll/KllDirectLongsSketch.java @@ -19,6 +19,30 @@ package org.apache.datasketches.kll;
