Why I'm doing:

default current_timestamp broken after update to 3.3.2 from 3.2.10

What I'm doing:

mysql> CREATE TABLE migrations ( version_id bigint(20) NOT NULL COMMENT "", id bigint(20) NOT NULL AUTO_INCREMENT COMMENT "", is_applied boolean NOT NULL COMMENT "", tstamp datetime NULL DEFAULT CURRENT_TIMESTAMP COMMENT "" ) ENGINE=OLAP PRIMARY KEY(version_id, id) DISTRIBUTED BY HASH(id) ORDER BY(version_id) PROPERTIES("replication_num" = "1");
Query OK, 0 rows affected (0.04 sec)

mysql> insert into migrations (version_id, is_applied) values (0, true);
Query OK, 1 row affected (0.39 sec)
{'label':'insert_2c42bf7a-6f3b-11ef-afc1-024253f5d68c', 'status':'VISIBLE', 'txnId':'2093'}

mysql> select * from migrations;
+------------+------+------------+---------------------+
| version_id | id | is_applied | tstamp |
+------------+------+------------+---------------------+
| 0 | 1 | 1 | 2024-09-10 11:39:00 |
+------------+------+------------+---------------------+
