library-based. If there is more than one schema in the DB instance, this setting can have a significant increase in the speed of slave replication. In general, a single-Library multi-table is a more common situation,The library-based concurrency has no OVA. The core idea is that the data of the tables under different schemas will not affect each other, that is, the slave node can use the relay log in a different Schema each assigned a similar SQL fun
