kdb database disk space

Hi everyone,

I just generated a 8.2G partitioned table from .csv.gz files of size 742M. I know that there is a compression tool in kdb but I was wondering why the database size is expanding more than 10 times? 

How do you usually manage disk space of your databases?

thanks

default is uncompressed (for speed)

compression is as simple as setting .z.zd before or in your script

.z.zd:17 2 5

or similar
