sleeps and waits for the primary server to generate new events,which the I/O thread writes to the relay log. SQL handles the last step of the process from the thread, and the SQL thread reads the events from the log and replays the events in them to update the data from the service so that it is consistent with the data in the master service. As long as the thread is consistent with the I/O thread, the trunk log is typically located in the Os cache,

Asynchronous replication means there is a delay in copying data from one machine to another-most importantly this means that the data cannot be copied/applied to the slave at the same time when the application's transaction commit has been confirmed. Typically, this delay is dete
