Amazon SageMaker Data Wrangler

Amazon SageMaker Data Wrangler provides a visual and programmatic environment for importing, profiling, transforming, and exporting machine learning data. It helps practitioners prepare structured datasets for customization and evaluation with reusable transformations.

Key points

  • Data flows record ordered preparation steps
  • Built-in analyses reveal leakage, imbalance, and data quality issues
  • Flows can export processing code or jobs into SageMaker workflows

When to use it

  • Prepare a preference dataset for model tuning
  • Normalize structured evaluation features and inspect class imbalance

Exam tips

  • Choose Data Wrangler for interactive ML data preparation and Glue for broad managed data-lake ETL
  • Fit transformations only on training data where leakage would invalidate evaluation

Mode

Exam fidelity: AWS lists multiple choice and multiple response for this exam. Ordering, matching, and case-study items are supplemental learning exercises; their results stay in overall study accuracy but do not count toward exam-style accuracy. Difficulty labels describe this site's scenario complexity, not an AWS-published question rating.
