In new version MySql database there are many new features and One of top feature in MySql is multi-source replication with multi source replication we can you can point multiple master server to slave so limitation of slave having only one master is lift off. MySql also have nice blog post written by my colleague on multi source replication you will find useful and also show the status of blog. Shows salve status also returns immediately without waiting for stop salve. There is now a different method for parallel replication. With new implementation the slave can apply transaction in parallel with single database or schema too. Check slave_parallel_type for details. In MySql there is Global Transaction Identifiers that automatically tracks the replication position in replication stream.
