What's Wrong?

Create table

CREATE TABLE IF NOT EXISTS test_cloud_mow_new_tablet_compaction (
      `k1` int NOT NULL,
      `c1` int,
      `c2` int,
      `c3` int
      )UNIQUE KEY(k1)
  DISTRIBUTED BY HASH(k1) BUCKETS 1
  PROPERTIES (
      "enable_unique_key_merge_on_write" = "true",
      "disable_auto_compaction" = "true",
      "replication_num" = "1");

Do schema change:

alter table test_cloud_mow_new_tablet_compaction modify column c1 varchar(100);

load and schema change concurrent execution：

insert into test_cloud_mow_new_tablet_compaction values(1,99,99,99);

Result is incorrect:

mysql> select * from  test_cloud_mow_new_tablet_compaction;
+------+------+------+------+
| k1   | c1   | c2   | c3   |
+------+------+------+------+
|    1 | \N  |   99 |   99 |
+------+------+------+------+
 rows in set (0.08 sec)

What You Expected?

Result is correct:1,99,99,99
