DMSでDB移行の際にハマったタイムゾーン問題

Posted at

ソースDB

mysql> show variables like '%time_zone%';
+------------------+--------+
| Variable_name    | Value  |
+------------------+--------+
| system_time_zone | JST    |
| time_zone        | SYSTEM |
+------------------+--------+

ターゲットDB

mysql> show variables like '%time_zone%';
+------------------+------------+
| Variable_name    | Value      |
+------------------+------------+
| system_time_zone | UTC        |
| time_zone        | Asia/Tokyo |
+------------------+------------+

問題

  • source DB の timestamp が - 18 時間されて target DB に挿入されてた
  • これを extra attribute でsession の timezone を直した
  • source DB の timestamp が +9 時間されて target DB に挿入されるようになった
