Subject [jira] [Commented] (HIVE-8128) Improve Parquet Vectorization
Date Tue, 03 Mar 2015 08:43:08 GMT

    [ https://issues.apache.org/jira/browse/HIVE-8128?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14344743#comment-14344743

Dong Chen commented on HIVE-8128:
---------------------------------

Hi,

I upload a POC at: https://reviews.apache.org/r/31671/

This POC is based on the new vectorized Parquet API at https://github.com/zhenxiao/incubator-parquet-mr/pull/1

I check out the latest Parquet API code in [~zhenxiao]'s github repo (vector branch), make
a little change, and then add the Hive changes. The vectorized read could work locally!

This patch covers the basic workflow and Int type. A list of TODO is commented in the code.

Any feedback is welcome!

which was partially done in HIVE-5998.
