Hello, everyone. I want to know what role neo4j plays in the databub. I found that there is no neo4j in docker, and the datahub is running normally. No alarm is found

neo4j is basically used for the capturing of graph relationships in datahub (lineage etc) but there is an option to use Elasticsearch as the alternative -> check your gms env variable and see graph_service_impl is set to elasticsearch or neo4j

Thankyou for your reply😁
