MySQL’s master-slave replication and clustering solutions.

MySQL’s master-slave replication and clustering are two common solutions used to improve the availability and performance of databases.

Master-slave replication refers to setting one MySQL database server as the master server, and the rest of the MySQL database servers as slave servers. Operations on the master server will be replicated to the slave servers, thereby achieving data synchronization. Master-slave replication can be used to improve the database’s read performance, share the load on the master server, and enhance data reliability.

A cluster refers to multiple MySQL database servers being grouped together to collectively manage data. Clusters can improve the fault tolerance and scalability of databases, enabling load balancing and high availability. Typically, clusters will utilize technologies like MySQL Cluster or MySQL Group Replication to synchronize and manage data.

It is necessary to choose between master-slave replication or cluster solution based on specific needs and circumstances in order to achieve optimal performance and availability.
