[jira] [Created] (PARQUET-1365) Don't write page level statistics for v1

Gabor Szadovszky created PARQUET-1365:
-----------------------------------------

             Summary: Don't write page level statistics for v1
                 Key: PARQUET-1365
                 URL: https://issues.apache.org/jira/browse/PARQUET-1365
             Project: Parquet
          Issue Type: Improvement
          Components: parquet-mr
            Reporter: Gabor Szadovszky
            Assignee: Gabor Szadovszky


Page level statistics are never used in production and after adding column indexes they are completely useless. In page_v2 we are not able to remove the unnecessary statistics as they are required fields in the page header but in page_v1 it is optional. Let's get rid of the unnecessary and optional fields in the page headers.
