Hi @Walter_C ,

Thank you for your response over this issue.

I tried both the options:
- setting up the spark configuration at session level, but did not work
- used the replaceWhere option for a specific partition date, but that also did not work.

In both the cases, all bq table records are getting overwritten or deleted for all partition dates which is not acceptable.

I checked the spark bq connector documentation page, I could not find the 'replaceWhere' option as well.
