Replication is configured with the ReplicationHandler section in the Solr index configuration file
solrconfig.xml. CoreMedia Blueprint defines the ReplicationHandler for the config sets
"content" and "cae" in module apps/solr/modules/search/solr-config.
Blueprint default configuration of the ReplicationHandler references some system
properties that need to be set accordingly when starting a Solr instance that is part of a leader/follower setup.
solr.leader: set totruefor the Solr leader node, defaults tofalsesolr.follower: set totruefor Solr follower nodes, defaults tofalsesolr.leader.url: set to the Solr URL of the Solr leader node, for Solr follower nodes
Note, that hostname and port of the leader node must also be set in the solr.shardsWhitelist
system property of Solr follower nodes. Alternatively, the corresponding checks can be disabled with
-Dsolr.disable.shardsWhitelist=true. See the Solr Reference Guide for details.
When developing with CoreMedia Blueprint, you can start Solr locally from Maven as described in
Section 3.1, “Starting”. You can also start a Solr follower node to test replication
in the same way by invoking "mvn exec:exec@start-solr-follower". Under the hood, this will set the
above system properties. See the configuration of the exec-maven-plugin in
file apps/solr/modules/search/solr-config/pom.xml for details.
