trying to specify or infer best compression technique per column much harder
and something that can be done later

Here we mentioned that, this improvement will be implemented later.
Could you please point me the right JIRA, where we started implementing this
point or discuss?

> column based storage has been proven a better storage layout for OLAP.
> Hive does a great job on raw row oriented storage. In this issue, we will
> enhance hive to support column based storage.
> Acctually we have done some work on column based storage on top of hdfs, i
> think it will need some review and refactoring to port it to Hive.
> Any thoughts?
