Which two statements are true about MySQL server multi-source replication?

In a multi-source replication setup, MySQL relies on the relay_log_recovery option to enable or disable automatic relay log recovery just after server startup, which helps in resilient operations. Also, MySQL does not have a built-in mechanism to detect or resolve conflicts if the same data is modified by transactions from different sources. It’s the responsibility of the database administrators to ensure that the data modified by each source is distinct to avoid conflicts.
