If set to 0, storage engines can (but are not required to) assume that duplicate keys are not present in input data. Set to 0 to speed up imports of large tables to InnoDB. The storage engine will still issue a duplicate key error if it detects one, even if set to 0. | NULL | NULL | NULL | OFF,ON | NO | NULL | NULL |

|
| 11. | GTID_IGNORE_DUPLICATES | NULL | OFF | COMPILE-TIME | OFF | GLOBAL | BOOLEAN | When set, different master connections in multi-source replication are allowed to receive and process event groups with the same GTID (when using GTID mode). Only one will be applied, any others will be ignored. Within a given replication domain, just the sequence number will be used to decide whether a given GTID has been already applied; this means it is the responsibility of the user to ensure that GTID sequence numbers are strictly increasing. | NULL | NULL | NULL | OFF,ON | NO | OPTIONAL | NULL |
