                 URL: https://issues.apache.org/jira/browse/IMPALA-13497

          Components: Backend
    Affects Versions: Impala 4.5.0
            Reporter: Joe McDonnell

The size of the tuple cache entry written / read is useful information for 
understanding the performance of the cache. Having this information in the 
profile will help us tune the placement policy for the tuple cache nodes.
