janusgraph_<index_name>. I would like to change the prefix for all indices to something like jgtest1_<index_name>.index.search.elasticsearch.index-name = jgtest1GLOBAL_OFFLINE option, so I stopped the server, changed the Cassandra keyspace name to create a new DB, and then restarted the server. After defining the schema and mixed indices the ES index names are still the same as before. Namely the prefix of the indices that are create is still janusgraph_, instead of jgtest1_. Isn't the index-name option supposed to work? Am I missing somthing?
