From version 2.0.2, the custom <SOLR6_INSTALL_LOCATION>/contentstore folder has been removed. Metadata, Permissions, and Content for the Alfresco Repository nodes are fully stored in the SOLR Core standard indexes.
Since the total amount of storage could be equivalent between previous versions, the SOLR Core Index storage has been increased. In order to control the size and the performance of the SOLR index, the following actions may be performed:
- Disable document FINGERPRINT reduces storage requirements
- Disable SOLR Document Cache reduces RAM requirements
- Optimize SOLR Index improves search performance
Additionally, from version 2.0.2, SOLR Merging parameters have been exposed that can be configured within the solrcore.properties file. The default values function adequately for many use cases, however some recommendations are given to increase performance in large deployments.
