####MySQL跳过 1032 1062错误slave_exec_mode(global级别) IDEMPOTENT or STRICT
Controls how a slave thread resolves conflicts and errors during replication. IDEMPOTENT mode causes suppression of duplicate-key and no- key-found errors; STRICT means no such suppression takes place.
IDEMPOTENT mode is intended for use in multi-master replication, circular replication, and some other special replication scenarios for NDB Cluster Replication. (See Section 21.6.10, “NDB Cluster Replication: Multi-Master and Circular Replication”, and Section 21.6.11, “NDB Cluster Replication Conflict Resolution”, for more information.) NDB Cluster ignores any value explicitly set for slave_exec_mode, and always treats it as IDEMPOTENT.
In MySQL Server 5.7, STRICT mode is the default value.
or storage engines other than NDB, IDEMPOTENT mode should be used only when you are absolutely sure that duplicate-key errors and key-not-found errors can safely be ignored. It is meant to be used in fail-over scenarios for NDB Cluster where multi-master replication or circular replication is employed, and is not recommended for use in other cases.
