Specifically, I'm wondering if you can connect the Wolfram language to Elastic Search. Indication is that you can connect Wolfram to any DB that supports JDBC: https://reference.wolfram.com/mathematica/DatabaseLink/tutorial/DatabaseReference.html#14146
...but I'm having trouble determining if / how to make that connection. I know you ES can connect to other databases through JDBC, but can you connect and interact with ES through a JDBC connection?
(Of course, you can also go through the HTTP layer, so as a followup: would it be more performant?)
