Reason: ======= - InnoDB DML commit aborts the server when InnoDB does online virtual index. During online DDL, concurrent DML commit operation does read the undo log record and their related current version of the clustered index record. Based on the operation, InnoDB do build the old tuple and new tuple for the table. If the concurrent online index can be affected by the operation, InnoDB does build the entry for the index and log the operation. Problematic case is update operation, InnoDB does build the update vector. But while building the old row, InnoDB fails to fill the non-affected virtual column. This lead to server abort while build the entry for index. Fix: === - First, fill the virtual column entries for the new row. Duplicate the old row based on new row and change only the affected fields in old row based on the update vector. |
