Thank you for your interest! It is true that the tool supports mainly relational database systems. I don't quite understand what ElasticSearch support could mean? Is ElasticSearch a DBMS at all, or just a search engine? I'm sorry if this question is stupid, but I've really never had anything to do with ElasticSearch.

Yes, ES is a search engine, but under the hood it's really just a non-relational DB with Lucene on top of it. I guess what I would love to see is being able to see a visual representation of the relation between different fields. (Since ES is not relational, you obviously have to define these relations yourself). There are, for example, a aggregation functions at your disposal (https://www.elastic.co/guide/en/elasticsearch/reference/curr...) ES offers a tool called Kibana that lets you run these functions on top of your data (and even visualize it), but I never actually liked it because it's pretty cumbersome.
