The network traffic of full node replication from single machine to cluster session management mode one is increasing with the increase of the number of nodes, and it is precisely because of this factor that it is impossible to build larger clusters, in order to make the cluster nodes more larger, The first solution is the data replication traffic growth problem, the following will describe another way of

Label:The extract part is shown here, as below, What's the difference in using Clustervs using replication? In a replication system, one MySQL master server updates one or more slave servers. The transactions are committed sequentially, so a slow transaction can cause the server to lag behind the primary server for a period of time. This also means that if the primary server fails, Then from the server may be missing the last small portion of the transaction log. If you are using a transactional
