What changed in BigQueryInsertJobOperator? The two images look the same to me.

Yes, they are the same. Nothing changed in BigQueryInsertJobOperator.

I guess my question is, why are the screenshots attached if nothing changes there?

[avkirilishin]

To emphasize that the functionality from #17321 is not broken

[uranusjr]

I see, thanks for the clarification.

Hi, first of all thanks for the fix! What is the expected timeframe to see this one merged?

@peloyeje I guess it will be there as soon as the author (@avkirilishin ) rebaases it and fixes the static checks that were failing. Or if the author does not do it, maybe someone (you @peloyeje ) take it over and lead it to completion.

All right no problem will do :)

Hi @potiuk here you go! #22854
Let me know if everything is ok, it's my first time here

[potiuk]

Static checks failing - I recommend to rebasem and run pre-commit locally to test it.

Hi @potiuk!
AFAIK I'm not allowed to push into avkirilishin's branch (can I?) so I opened this PR instead: static tests are supposed to be ok on this (breeze static-checks --last-commit pass) + I rebased on latest upstream
