Best Practice Using Galera Cluster

[Garry Williams]

We have just set up a Galera Cluster on three geographically diverse servers.

How should we modify Perl clients to take advantage of this?

The DBD::mysql manual page gives no indication that we can specify a
cluster (or multiple hosts) instead of a host.  I have concluded that
we need to modify client code to handle failures and retries on
different hosts.

Any suggestions otherwise?
