[jira] [Created] (ARROW-6495) [Plasma] Use xxh3 for object hashing

Antoine Pitrou created ARROW-6495:
-------------------------------------

             Summary: [Plasma] Use xxh3 for object hashing
                 Key: ARROW-6495
                 URL: https://issues.apache.org/jira/browse/ARROW-6495
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++ - Plasma
            Reporter: Antoine Pitrou


We recently vendored xxh3 in Arrow. Plasma may want to use it for object hashing, since it's supposed to be even faster than XXH64.
See https://fastcompression.blogspot.com/2019/03/presenting-xxh3.html for performance numbers.
