compression

[scipio]

Hello

I am using MyISAM on a table that look somewhat like this

cl_id , cl_feature , cl_some_other_feature , ... , cl_data

were the features are integers or datatimes and the data is text fields about 5-25k most of it is blanks.
(foot print after compression with winrar is about 5-10%)

I would like to have the data compressed.

one possible way to do it is change the data so that it will be binary COMPRESS()ed data but i want the compression to be transparent if possible does MySQL has a feature to compress a single column in transparent way?
