AWS Certified Data Engineer – Associate (DEA-C01) — Question 114

A data engineer is building an automated extract, transform, and load (ETL) ingestion pipeline by using AWS Glue. The pipeline ingests compressed files that are in an Amazon S3 bucket. The ingestion pipeline must support incremental data processing.

Which AWS Glue feature should the data engineer 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 allow AWS Glue to track the state of processed data, enabling incremental data processing by remembering which files have already been ingested. The other options, such as Workflows and Triggers, are useful for managing the execution flow and scheduling but do not specifically handle incremental processing of data.
