Looking for a tool for faster aws glue test iterations

I'm building several glue jobs for a full database migration to a new database with different schema (but similar business logic).

Glue is a powerful tool, however it's painful the time I need for each iteration to test something I did. If I want to run the job it averages between 2 mins and 6 minutes (based on the job and the amount of relations and data).

I found out I can use the data preview session. This made it faster to test changes, however we're still talking about 30 seconds for each refresh of the session (and more than a mintue for first run) + the data preview doesn't attempt to insert into the destination DB so some issues (unique constraint problems, etc..) won't appear until I do the actual job run.

Is there a best practice or tool that I can use to mimick the glue jobs but have them react in a much faster way?

p.s. I tried to use bigger and more workers in the job but still we're talking about >1 minute durations even with that.
