I created a PR #176 for this, however don't know how to update the tests to try the new change, if you happen to know how to do it quickly maybe you can add some tests

With mysql try to configure the socket. This might help: https://superuser.com/questions/1411402/how-to-expose-linux-socket-file-from-docker-container-mysql-mariadb-etc-to

Thanks, will work on it tomorrow

Any update on this issue?

Stale issue message

I am continuing the work on this in #319 so reopened the issue.
Thanks @andy-yx-chen and @czp3009 for previous impl (that was not yet merge but part of the current effort) in #176 and #285.

In the api side the current PR adds socketPath to Configuration. I am thinking if this is the most clear approach as in this case host + port are redundant.
Also the current impl fallback to host port in case of some problems (when fallback to nio) and maybe this should be made more explicit.

Lastly, the current PR does not have Postgres tests in case someone wants to contribute that. Otherwise the current PR will be merged without integration test for postgres (which is relatively minor part of the current change, but require setup effort).

Implemented in 2.1.6. Thanks @andy-yx-chen and @czp3009!
