Manuel Lenormand commented on SOLR-5501: ---------------------------------------- Hi [~noble.paul], I need an advice for this Jira in order to make sure this feature is compatible with SOLR-5381: 1. Should the role be in clusterstate.json or in an external roles.json? 2. API for setting hot/cold replicas is ok?
