MySQL 8 supports different replication methods but the traditional method is to replicate through binary logs of the master server. A binary log is a file that collects all the statements that attempt to change the table data. These statements will be executed on the slave servers to replicate the master data.

The daemon_memcached plugin has the capability to manage the binary log on the master server, and the same can be used for replication on slave servers. All Memcached commands are supported by binary logging.
