Deployment Architecture

Can you control what gets replicated between search heads?

I would like to know if there is a way to control what configurations are replicated between search heads in a search head cluster.

Yes! Via whitelists and black lists located in server.conf. These default stanzas control our default replications:
From Spec:

conf_replication_include. =

* Controls whether Splunk replicates changes to a particular type of *.conf file, along with any associated permissions in *.meta files.
* Defaults to false.

conf_replication_summary.whitelist. =

* Whitelist files to be included in configuration replication summaries.

conf_replication_summary.blacklist. =

* Blacklist files to be excluded from configuration replication summaries.

And our default values:

/opt/splunk/etc/system/default/server.conf conf_deploy_repository = $SPLUNK_HOME/etc/shcluster 
/opt/splunk/etc/system/default/server.conf conf_deploy_staging = $SPLUNK_HOME/var/run/splunk/deploy
