Hi all,

CREATE TABLE T (
  i INT,
  j INT
) WITH (
  'write-mode' = 'changelog'
);

The table can accept +I -U +U -D all changelog inputs. Paimon will
automatically maintain the LSM structure, updating, deleting, and
counting according to the entire row.

But this mode has very poor performance, so it should be compared
across the entire row.

I have never seen the use of this mode before, so I will discuss it
here. Do we still need it? Can you delete it?

Best,
Jingsong
