Date Tue, 24 Mar 2009 08:27:50 GMT

He Yongqiang commented on HIVE-352:
-----------------------------------

By "So i guess i may need to discard SequenceFile, which can support skipping data and compression.
" I mean:

i may need to discard SequenceFile, and implement a new one, which has many similarities with
SequenceFile but can support skipping data and fine grained compression (in record each column
compression).

> 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?
