What Are the Biggest Challenges You've Faced With Your ETL Pipeline? or How Do You Optimize Performan

Wow, these are all gold!

Definitely gonna try mocking data and adding more validation checks—my pipeline’s been failing on nulls lately, so that might be the fix.

Also, *yes* to visualization. I’ve been meaning to try Airflow’s UI instead of staring at logs like a caveman.

Thanks y’all! 🙌 (Still not restarting it tho.)
