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


Dong Chen commented on HIVE-8128:


I upload a POC at:

This POC is based on the new vectorized Parquet API at

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!
