Cause: shared federatedx_io cannot store table-specific data. Fix: move current row reference `federatedx_io_mysql::current` to ha_federatedx. FederatedX connection (represented by federatedx_io) is stored into federatedx_txn::txn_list of per-server connections (see federatedx_txn::acquire()). federatedx_txn object is stored into THD (see ha_federatedx::external_lock()). When multiple handlers acquire FederatedX connection they get single federatedx_io instance. Multiple handlers do their operation via federatedx_io_mysql::mark_position() and federatedx_io_mysql::fetch_row() in arbitrarty manner. They access the same federatedx_io_mysql instance and same MYSQL_ROWS *current pointer, so one handler disrupts the work of the other. Related to "MDEV-14551 Can't find record in table on multi-table update with ORDER BY". |
