Chapter 8. Managing Replication

234

replication is very useful for balancing heavy traffic loads or to keep master servers based locally in
geographically-distributed environments.

Figure 8.4, “Cascading Replication”

shows an example of a simple cascading replication scenario,

though it is possible to create more complex scenarios with several hub servers.

Figure 8.4. Cascading Replication

For information on setting up cascading replication, see

Section 8.6, “Configuring Cascading

Replication”

NOTE

Multi-master and cascading replication can be combined. For example, in the multi-master
scenario illustrated in

Figure 8.2, “Multi-Master Replication (Two Masters)”

, Server C and

Server D could be hub servers that would replicate to any number of consumer servers.
