No individual pings, please, kindly keep it to all. Thanks.

You'd have to set it as a header, just like with the other REST APIs - see reference documentation - and you'd get back the value as a header. Though I assume you did that -- did it not work?

Thanks,
I use jdbc not REST API,so I don't know where to set it in jdbc connection

I think that's currently not possible, JDBC doesn't take a configuration property for that, unfortunately. Feel free to open an issue / feature request on Github, though.

As a hacky alternative, I guess you could SELECT a unique literal token in the SQL query itself, if that's at all feasible, to help correlate requests and responses.
