The Liferay Cross-Cluster Replication module allows Liferay DXP to perform read operations on a local Elasticsearch cluster that has been configured to replicate the indexes of a remote cluster. This module leverages Elasticsearch's Cross-Cluster Replication feature for replicating search indexes on distributed cluster. CCR is used primarily for Disaster Recovery and Data Locality (geoproximity for read operations) purposes.
