I’ve asked this before and wasn’t quite sure on the answer but is it better to connect to crate via posgresql or via http endpoint? I have concluded some tests and it seemed that HTTP was quicker, but in some cases postgres was quicker once the connection was opened. I believe Dominic may have suggested HTTP was a better option but I’m just wondering if there were any changes to this at all.

Here is an example of how you can interact using java.
