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.

The fastest way to develop on a real environment (not a docker or local) is using Glue Notebooks which are based on Interactive sessions.

  • I havent' tried the glue notebooks. Will try to check them out. Thanks



As per your usecase where you want to avoid running the complete glue job to test the code you can utilize glue interactive sessions [+] https://docs.aws.amazon.com/glue/latest/dg/interactive-sessions-gs-notebook.html

Glue interactive sessions help our customers to test individual snippets of code and debug the code in real time.

  • Sessions are better but still take time and don't test the actual insertion. But they're an improvement over running the job all together for sure. Thanks
