[Bug]: When there duplicate records exist in table, the spark upsert can't merge record

[baiyangtx]

What happened?

If the table already has some records with duplicate primary key, then using spark insert into sql to do upsert will not work as expected. rows still are duplicated but expected to be merged into one.

I can't reproduce it in 0.4.1.

CREATE TABLE IF NOT EXISTS user (
    id INT,
    name string,
    ts TIMESTAMP,
    PRIMARY KEY(id)
) USING arctic 
PARTITIONED BY (days(ts));

insert overwrite db.user values (2, "frank", timestamp("2022-07-02 09:11:00"));
...
insert into db.user values (2, "frankkkk", timestamp("2022-07-02 09:11:00"));
insert into db.user values (2, "frankkkk", timestamp("2022-07-02 09:11:00"));

alter table db.user set tblproperties (
    'write.upsert.enabled' = 'true');

insert into db.user values (2, "llllll", timestamp("2022-07-02 09:11:00"));
