             Summary: Upgrade DataSketches to version 3.1.0
                 Key: IMPALA-10863
                 URL: https://issues.apache.org/jira/browse/IMPALA-10863

          Issue Type: Improvement
          Components: Backend
    Affects Versions: Impala 4.1.0
            Reporter: Fucun Chu


https://github.com/apache/datasketches-cpp/releases/tag/3.1.0 has some important bug fixes, and a Theta sketch feature to avoid some cost of deserialization. This feature can speed up Theta union operations.

Update the external DataSketches files to version 3.1.0.
