In the previous blog, we were able to setup a MySQL NDB Cluster
replication between one source and one replica cluster. In this
blog, we will discuss about replication between one source and
three replica clusters.
Note: With MySQL version (8.0.21), we have started changing the term “master” to “source”, the term “slave” to “replica”. So in this blog we will refer these terms ‘source’ and ‘replica’ wherever applicable.
The main advantage of this type of topology is good for giving ‘local’ reads in geographically distant areas as well as increased redundancy in case of issues.
Let’s create four MySQL NDB Cluster with the following environment, from which one will be termed as ‘source’ cluster while the rest will be ‘replica’ clusters.
- MySQL NDB Cluster version (Latest GA version)
- 1 Management node
- 4 Data nodes …
