Whether the slave should replicate events that were created with @@skip_replication=1 on the master. Default REPLICATE (no events are skipped). Other values are FILTER_ON_SLAVE (events will be sent by the master but ignored by the slave) and FILTER_ON_MASTER (events marked with @@skip_replication=1 will be filtered on the master and never be sent to the slave).
