AWSAWS Certified Generative AI Developer - Professional2026-101.3 Implement data validation and processing pipelines for FM consumption

Analyze and Prepare Data with Amazon SageMaker Data Wrangler and Amazon EMR

Completed by opening the official lab

Why it matters

1.3.2 combines Data Wrangler insights with Glue and Lambda for input validation; this Lab is the hands-on Data Wrangler half of that pipeline, plus EMR for volume Lambda cannot absorb.

What to practise

Analyze and prepare a dataset in Data Wrangler, carry part of that preparation into EMR, and compare what each tool does with the same data.

How it fits

Data Wrangler is the profiling tool 1.3.2 names directly. EMR is general big-data background: 1.3.4 chooses between SageMaker Processing and Lambda for preprocessing compute, and neither covers EMR-scale volume, so use this Lab to see where that third option sits.
