AWS Certified Data Analytics – Specialty — Question 67

A data analytics specialist is building an automated ETL ingestion pipeline using AWS Glue to ingest compressed files that have been uploaded to an Amazon S3 bucket. The ingestion pipeline should support incremental data processing.
Which AWS Glue feature should the data analytics specialist use to meet this requirement?

Answer options

• A. Workflows
• B. Triggers
• C. Job bookmarks
• D. Classifiers

Correct answer: C

Explanation

The correct answer is C, Job bookmarks, as they allow AWS Glue to track the state of data that has been processed, facilitating incremental processing. Options A (Workflows) and B (Triggers) are used for managing and scheduling ETL jobs but do not handle state tracking, while D (Classifiers) is used for schema inference, not for managing data processing state.
