We test gz also,but when we use gz,it seems will cause memory out of usage.

Ah, sorry. 550 mio. rows and not billions.

After our tests with ~550 bill. rows, we probably will go
Subject: Re: GZ better than LZO?
For what's it worth I had similar observations.
I simulated heavy write load and I found that NO compression was the
fastest, followed by GZ, followed by LZO.
After the tests I did a major_compact of the tables, and I included that time
in the total.
Also
32MB. Does that difference dominate the computational cost of decompression?

Hello,
we simulated real looking data (as in our expected production system) in
respect to row-key, column families ...
The test client (TDG) basically implement a three

Are you getting this results because of the nature of test data generated?
Would you mind sharing some details about the test client and the data it
generates?
