What's wrong?
When I add a primary key constraint to a columnar type table, the compression rate is greatly reduced (the table goes from being able to be compressed to about 800MB to only being able to be compressed to 19GB), what is the best way to maintain the original compression rate if I have to add a primary key constraint?help me pls.
