Hey Buddy!!
U r mistaken we can only compress 255 distinct values per
column plus nulls(by default).
Compressed values are stored in table header.
also compression cannot be done on primary index columns
and alter table does not support compression on existing
columns.
Compression works with multi-set tables.
