How does MySQL replication work?

Replication works as follows: Whenever the master’s database is modified, the change is written to a file, the so-called binary log, or binlog. The slave has another thread, called the SQL thread, that continuously reads the relay log and applies the changes to the slave server.

Do I need MySQL router?

What is MySQL group replication?

MySQL Group Replication is a MySQL Server plugin that enables you to create elastic, highly-available, fault-tolerant replication topologies. There is a built-in group membership service that keeps the view of the group consistent and available for all servers at any given point in time.
