AWS 筆記 - DB Instance XXXX contains MyISAM tables that have not been migrated to InnoDB. These tables can impact your ability to perform point-in-time restores. Consider converting these tables to InnoDB

先查看有哪些 table:

mysql> SELECT TABLE_NAME, ENGINE FROM information_schema.TABLES;
+----------------------+--------------------+
| TABLE_NAME           | ENGINE             |
+----------------------+--------------------+
...
| pma_bookmark         | MyISAM             |
| pma_column_info      | MyISAM             |
| pma_designer_coords  | MyISAM             |
| pma_history          | MyISAM             |
| pma_pdf_pages        | MyISAM             |
| pma_recent           | MyISAM             |
| pma_relation         | MyISAM             |
| pma_table_coords     | MyISAM             |
| pma_table_info       | MyISAM             |
| pma_table_uiprefs    | MyISAM             |
| pma_tracking         | MyISAM             |
| pma_userconfig       | MyISAM             |
...

結果發現是 PHPMyAdmin 的那些 tables，由於這些影響不大，就操刀吧！以 pma_bookmark 為例

mysql> ALTER TABLE  `phpmyadmin`.`pma_bookmark` ENGINE = INNODB;

收工。
