What Are Your Biggest Challenges When Working with ETL Pipelines? or How Do You Optimize Performance

Ugh, the "API changed its response structure" pain is too real.

I now dump raw API responses to S3 before transforming them. That way, if something breaks, I can replay the pipeline without hitting rate limits.

Also, Fivetran handles a lot of the connector headaches for me. Worth the $$$ if you’re tired of duct tape.
