I’ve been trying a lot to find a solution to establish connection between glue job and RDS postgresql but all the solutions are using glue catalog which I don’t want to use.

I only want to establish a connection and send some data from glue job (spark script) to my RDS database. I have already created the tables in my RDS database now I want to just send the data to it. How should I approach it?

Also I found some articles/videos to do this using jdbc but none of them are using glue job script. Please help me out.
