I know it is a bit late, but why are we not setting the configurations directly?

the reason why I created the properties object was to have it in a synchronized block, but since we are in a lazy val it is probably useless...

@mgaido91 can you send a followup PR to clean it up? Now we can't set the SQL confs in a batch and I don't think it's useful to have this Properties.

@hvanhovell and @mgaido91 . Feel free to make a follow-up if we need. Also, please apply that in the backporting PR, #25734, before merging for consistency.
