Subject Re: AO and Parquet Format

Briefly, parquet format is organized by row groups, each row group is Column-oriented. And
AO is Row-oriented, I guess it's very similar to PG heap format.

Do you want the detailed introduction of format?
Seems it doesn't have a details format wiki/doc of hawq, maybe Lili Ma have some resources.

I am very interested in it also, let's discuss it in this mail-list in future.
Thank you!

Hi, guys!

I want to ask more detail about AO and Parquet Format in HAWQ.

As we know, in PostgreSQL, tuples is organized one by one in a fixed size block when the table
format is heap. What about AO and Parquet?

Thanks for any advice!:)
