Service metadata can be exported to an ElasticSearch server for advanced search functionality. While the connection to ElasticSearch is active, the Service Registry keeps the metadata records in ElasticSearch in synchronized state with the Service Registry database. The ElasticSearch connection does not modify any data in the Service Registry. The data in the Service Registry are always treated as the master data, and the data stored in ElasticSearch are updated to reflect the current state of the Service Registry data.
