Problem: ======= - InnoDB modifies the PAGE_ROOT_AUTO_INC value on clustered index root page. But before committing the PAGE_ROOT_AUTO_INC changes mini-transaction, InnoDB does bulk insert operation and calculates the page checksum and store as a part of redo log in mini-transaction. During recovery, InnoDB fails to validate the page checksum. Solution: ======== - Avoid writing the persistent auto increment value before doing bulk insert operation. - For bulk insert operation, persistent auto increment value is written via btr_write_autoinc while applying the buffered insert operation. |
