We still only support actively into one cluster cluster, but have the ability to switch indexing clusters and cdcr will replicate correctly > Enabling bi-directional CDCR on cluster for better failover > ----------------------------------------------------------- > > Key: SOLR-11003 > URL: https://issues.apache.org/jira/browse/SOLR-11003 > Project: Solr > Issue Type: Improvement > Security Level: Public(Default Security Level.
