[GitHub] [orc] autumnust opened a new pull request #512: [ORC-638] Enlarge MultiValueColumnVector with factors when child arraySize is not enough

autumnust opened a new pull request #512:
URL: https://github.com/apache/orc/pull/512


   Issues are described in ORC-638. 
   The factor "3" is chosen based on heuristic. 
   
   The better approach is to create averageListElementSize in columnVector in hive-storage-api, but as the users of `ColumnVector` it also makes sense to enlarge the child array more aggressively.
