CDCR (Cross Data Center Replication) has been a long requested feature in Apache Solr. In this talk, we’ll discuss the new CDCR support in Solr 7. Legacy versions of Apache Solr (Solr 6.6 and below) had no out of the box offerings for enabling DR (disaster recovery) plans as far as data in Solr indexes were concerned. Solr 6.6 introduced the possibility of enabling your application for DR, while SOLR 7.2 took it to the next level by adding bidirectional syncs. At this meetup, we’ll demonstrate the features of CDCR, its potential benefits, use cases and constraints. We will discuss the do’s and don’ts of CDCR and demonstrate CDCR on AWS.
