------------------------------------

             Summary: Add support for Puffin File writer
                 Key: IMPALA-14755
                 URL: https://issues.apache.org/jira/browse/IMPALA-14755
             Project: IMPALA
          Issue Type: New Feature
            Reporter: Peter Rozsa
            Assignee: Peter Rozsa


Puffin is a lightweight container format for arbitrary binary blobs, and its implementation is a prerequisite for supporting the Iceberg V3 spec. Specifically, it enables the storage of Deletion Vectors as sidecar files and provides a standardized container for Column Statistics (e.g., Apache DataSketches Theta blobs).
