Show the mock tables used by NDB  to support foreign_key_checks=0 . When this is enabled, extra warnings are shown when creating and dropping the tables. The real (internal) name of the table can be seen in the output of SHOW CREATE TABLE . 

• ndb_slave_conflict_role

Deprecated in NDB 8.0.23, and subject to removal in a future release. Use ndb_conflict_role instead. 

• ndb_table_no_logging

When this variable is set to ON  or 1 , it causes NDB  tables not to be checkpointed to disk. More specifically, this setting applies to tables which are created or altered using ENGINE NDB  when ndb_table_no_logging  is enabled, and continues to apply for the lifetime of the table, even if ndb_table_no_logging  is later changed. Suppose that A , B , C , and D  are tables that we create (and perhaps also alter), and that we also change the setting for ndb_table_no_logging  as shown here: 

SET @@ndb_table_no_logging = 1; CREATE TABLE A ... ENGINE NDB; CREATE TABLE B ... ENGINE MYISAM; CREATE TABLE C ... ENGINE MYISAM; ALTER TABLE B ENGINE NDB; SET @@ndb_table_no_logging = 0;
