Subject [GitHub] orc issue #78: ORC-128. Add getStatistics to Writer API
Date Thu, 19 Jan 2017 07:17:18 GMT
Github user prasanthj commented on the issue:

    @dain Hive already uses stats API (reader side and writer side) to get basic statistics
like (numRows, rawDataSize, etc.) from the footer to avoid row-by-row stats gathering. This
new API is to extend the same for column statistics (although ORC is missing NDV at this point).

If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at infrastructure@apache.org or file a JIRA ticket
with INFRA.
