Subject [jira] Created: (PIG-210) Column store
Date Thu, 17 Apr 2008 23:37:21 GMT
Column store

                 Key: PIG-210
                 URL: https://issues.apache.org/jira/browse/PIG-210
             Project: Pig
          Issue Type: New Feature
          Components: data
            Reporter: John DeTreville

I believe that Pig stores its tables in row order, which is less efficient in space and time
than column order in a data-mining system. Column stores can be more highly compressed, and
can be read and written faster. It should be possible for clients to store their tables in
column order.
