He Yongqiang updated HIVE-352:
------------------------------
Attachment: hive-352-2009-4-30-2.patch
hive-352-2009-4-30-2.patch changs all lists to java arrays,
1), 2) and 3) are done. If we change 4), it will needs extra func call.
The attached patch also changes some fields in the key part to from vint to int
(decode not-one-byte vint will needs extra work).

> 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?
